A little misunderstood chef

"oh come onnnn~ i wanna eat something you cook." Sans said with a pout as Frisk closed her book and raised an eye-brow. 

"You're either dumb or stupid. I'll go with both." She threw her book at him and it hit him right in the face. He had an unimpressed look. 

"i bet you cook deliciously~" He said, still trying to persuade her. 

"Sans. no." He smirked. 

"sans yes~" She face-palmed. 

"If i cook tonight will you leave me alone?" He nodded. She sighed and got up. She rolled her sleeves and they both walked to the kitchen. Gaster wasn't home until dinner-time and he told Sans to cook for him. That lazy-bones however, used that to his advantage. Papyrus came downstairs as well. 

"SANS! FRISK! I JUST FINISHED MY HOME-WORK! WOAH! HUMAN FRISK ARE YOU COOKING TODAY??" Frisk sighed. 

"Apparently, since someone won't leave me alone." Frisk rolled her eyes and looked at them. 

"So you want mexican food, something you usually eat, or you want me to pull out a recipe?" Sans and Papyrus looked at each other dumbfound. 

"uhh...mexican...?" Sans said, confused. Papyrus shrugged. 

"Enchiladas...? Taco? Burrito? You'll have to be specific." She leaned again the counter and crossed her arms. The skeletons were left dumbfound. Their father barely knew a few recipes. 

"first...one..?" Frisk shrugged. 

"Chicken enchilada it is." Frisk took out some vegetables and started chopping. That's where the magic started. Her hands were moving fast, swiftly, cutting perfect cubes. Papyrus got on his stool that he used to reach the cupboards to watch better. Sans raised his head, his attention solely on her hands. She didn't even seem to pay attention to what she was doing. Holy shit- 

"Hey Papy, wanna help? Grab for me some black beans, the tortillas i bought, the cheese...hmm avocado sounds good..." She said as she picked up the avocado. It looked like a brown pear. Frisk then got out some oil and flour, chili powder they didn't even knew they had, garlic powder, ground cumin, dried oregano, veggie stock and fine sea salt. Her hands moved quick to make the sauce for this recipe. She put them in a sauce-pan. Frisk and Gaster were usually the ones going shopping. Why? Easy. Frisk was good wit ingredients. Her sense of smell and taste were really good. That's why Gaster would take her with him. She knew better what to use for her own good. She had a weak stomach after all. Frisk put some of the sauce in a jar, since she made too much. She started baking the chicken. The way she moved to cut it in pieces, the swift seasoning and all of that. The two skeletons already knew they were eating something of quality instead of Gaster's food. Frisk wasn't even paying attention to them anymore. She was smiling lovingly, probably at memories. Then she snorted and remembered something. 

"Hey Sans...? Wanna know what else runs in my blood apart from food??" Frisk said. He raised a bone-brow as she took her phone and put on a song. What else could it be other than a song with a latino beat. Sans started chuckling. 

"please don't start dancing in the kitchen when you're literally holding a knife.." He said face-palming. However her playlist was full of this type of songs so they listened to it while she cooked. When she finally put the tray in the oven. Gaster entered the house. 

"Hey kids! Sans did you finish making dinner as i asked?" Gaster entered the kitchen and froze as he saw: 1. it was clean since Frisk actually kept clean after herself. 2. It smelled good. Gaster frowned. 

"Did you seriously make Frisk cook for you?" Sans shrugged. Gaster frowned and hit his son with a spoon in the head. Frisk laughed. They waited a bit and finally the food was done. When the skeletons started eating they froze. It was--

"holy shit this is is good." Frisk leaned back in her chair and took a bite of her own enchilada. Papyrus looked at it with interest. 

"WOAH! HUMAN FRISK THIS IS GREAT!!" Frisk chuckled. 

"This is truly the best thing that has ever been made in this house." Gaster said with wide eyes. And since then? She has been known as the best chef. Which meant on special occasions they would make her cook. Soon enough her friends found out as well. And there she is now, the one that can cook the best...but that also brings trouble in the kitchen.


 "please please please PLEASEEEEEEEEE!! come on frisk, it's the day of the dead or something right~? you said it yourselfff~ come onnn~ please??" Frisk was growing irritated at her boyfriend. 

"SANS GILBERT GASTER! ESCUCHARTE A TI MISMO! ESTÁS COMENZANDO ME TO COOK!! (listen to yourself! you are begging me to cook)" Sans frowned. 

"you know i don't understand you when you switch to spanish.." Frisk face-palmed. She got up and sighed.

"tienes suerte de que estoy cocinando para tu culo ingrato (you are lucky i am cooking for your ungrateful ass)" Sans looked awkwardly to the side. 

"righttt...will you do it??" He asked hopeful. She nodded. 

"I will...i will...." She got up from her spot and went to the kitchen. She started pulling out some ingredients. She might as well make something good. Tacos sounded nice. She knew Toriel took a liking in that type of food, even if she didn't want to admit it. But the brothers and Gaster were circling her like vultures. Frisk sighed and started with the beef for the tacos. However, the ingredients started quickly going missing. She one minute had a lot of beef composition and the second....

"WHAT THE FUCK?!" She said as she realized she was down to half of what she was supposed to have. And the culprit? Frisk didn't know but it was Sans. He teleported quickly and started eating some of it...however he didn't get it to half. That was Papyrus doing, with his brothers help of course. Frisk frowned at the now half empty bowl. She slammed her spoon on the counter and was going to leave, when she realized she needs to take out the tortilla shells out of the oven. She left them to cool on the counter an went out in the living room to hopefully find the culprit. Gaster was quick to get in the kitchen and steal a shell. Frisk got back defeated only to find more food was gone. She spurted in disbelief.

"I SWEAR TO GOD, YOU STEAL ANY MORE FOOD I WAS PERSONALLY MAKE YOU ALL DECORATIONS FOR CINCO DE MAYO" Frisk sighed and grabbed the bridge of her nose in irritation. Frisk started preparing more beef and was now focusing on the sauce. Frisk scrunched her nose up as she felt someone watching her. She sighed and looked behind her only to see no one. She quickly turned to her sauce...AND SOMEONE TASTED IT. She frowned and scratched the top of her head. 

"one more thing goes missing....i will kill them.." She was so happy when things finally stopped going missing and she could make a salad....well...so she thought. Her vegetable cubes would start being less then the time she watched them. She looked at the vegetables and frowned. 

"That's fucking it....YOU THINK YOU CAN EAT WHAT I COOK ON A HOLIDAY ONLY I FUCKING CELEBRATE GET HERE YOU LITTLE-- COME ON COWARDS FIGHT ME!!" Sans and Papyrus who were in the living room immediately looked at each other and ran. Sans teleported away and Papyrus jumped over the couch to get to his room. Frisk was about to give them a surprise her abuela thought her. It was called beating someone up with a chancla. She threw her foot up and caught the slipper in it. Gaster was exiting his room/workplace with a coffee thinking he could linger around the kitchen. When he saw Frisk he spurted his coffee and went back in. Frisk frowned and sighed. She entered the kitchen again and she screamed. The three skeletons were dead. 


"What even are we celebrating?" Undyne asked. Toriel shrugged. 

"As long as i get Frisk's cooking i'm perfectly fine." Said Gorgette. Frisk was sitting annoyed on an armchair. Gaster was the one bringing the food. Sans and Papyrus were looking away in guilt. Alphys chuckled. 

"H-How m-much d-did t-they s-steal t-the f-food?" Frisk laughed bitterly. 

"You don't want to know..." Frisk said, scrunching her nose up. That's when she saw Gaster bringing out a tray he shouldn't. 

"Wait Gaster. Those aren't for eating." Frisk said getting up and taking the tray. They had a different type of bread on it. Everyone looked confused at Frisk. She sighed. 

"The day of the dead helloooo?? We're here to honor the dead you animals." Frisk said crossing her arms. Asgore nodded. 

"This holiday needs to be celebrated not only because Frisk cooked." She sighed in relief. 

"Thank yo--" But her friends were already eating. Frisk frowned, scoffed and sat up, clearly annoyed. 

"You guys are the worst...." She put the breads in a basket she had ready the whole day. All the skeletons noticed it. Frisk took her jacket, rolled her eyes and left. Sans tilted his head in confusion. He teleported after her. 

"frisk...baby bones come on...it's just food. why are you leav-...ing?" Sans asked confused as Frisk was lighting up a candle. She smiled softly. 

"It's called the day of the dead for a reason dummy...Want to join?" Sans didn't know it meant traditions as well. He nodded, clearly willing to show some respect to half of her culture. That was his girlfriend. He didn't know this whole food deal and day meant something more. She smiled. 

"Come on, we have to build and ofrenda! Frisk took his hand gently as he gave him a candle and they walked towards waterfalls. He didn't say anything as they found a quiet place where she could put up the 'ofrenda'. Sans sat down and watched curiously as she took out things he has never seen Frisk have before.

"I haven't celebrated this since i cam down the underground since i never had what i needed. But remember me and Gaster did a trip to the surface? I got some stuff then." She smiled softly as she put down beautiful orange and yellow flowers with little skeletons and candles. She put some colorful banners as well. Sans watched with attention.

"This? Is a cempasúchil..you might however know it as marigolds...we call it la flor de muerto..." Frisk came to him and smiled. 

"Skeletons are actually a really used decoration and detail on this day...But more...mexican...I actually wanted to ask if you would...mind...me painting your face??" Sans sockets widened. 

"what? no no no..it's fine! no need to ask." Frisk took out a few colors and started paining on his skull. The brush tickled. She set the brush aside and as Sans watched his reflection his smile softened. It was so flowery and colorful. Heh...She then pulled out two sugary skulls. 

"Here! I..i made two just in case. It's called a sugar skull!! You write the name of the person you are remembering on it's skull. Here!" She gave him a blue icing bag. She had a red one. Sans started slowly writing his mothers name. 

"soo...what's with this altar thing?" Frisk hummed. 

"Families select a variety of offerings which supposedly encourage the deceased to return home and hear the prayers of their loved ones." Sans chuckled. 

"and instead of weeping you guys celebrate the fact they're in a better place??" Frisk chuckled. 

"Exactly! Today is supposedly the day where the barrier between spirit world and human world is thinner like Halloween or Hallows Eve. Here! pan de muertoThankfully, this is not bread made of dead people, no matter what the name might lead you to think. It’s actually lightly orange-flavored sweet bread.." Sans chuckled as they both rpped one in two and set a few next to the tiny altar. Sans sighed and rubbed his neck awkwardly. 

"shit- umm..i've been disrespecting half of your culture almost the whole day...i'm sorry..." Frisk smiled and nodded. She sat both sugar skulls on the altar. 

"Calacas are clothed, decorated and colorful skeleton figurines...i just made you mine. I think you're part of this culture just as much as the rest of the altar." Sans sighed and kissed her forehead. 

"you're too nice..." He said. 

"One of the traditions is sharing stories of the dead...want to...share some?" Sans smiled. 

"i would love to, baby-bones....i would love to...."

And that's how they spent the night. Eating sweet bread and mexican candies Frisk got from the Surface as well as in saying a prayer and sharing stories. Frisk even showed him some songs and dances that would be played. It was a good night and now? The little chef wasn't so misunderstood anymore. However Sans had a bone to pick with the other monsters when they finally got home the next day.
