Dimitri:

He's gonna eat it all up! Even if it tastes bad he doesn't care. Whatever you put work in should be appreciated. Plus when out on the field it's not as if there is always delicious food so they should get used to bland and/or disgusting food.

Dedue:

He chewed it, thinking, then swallowed it. He has tasted it and realized where you went wrong now. He guided you to the kitchen, assuring cooking is not for everyone but everyone can cook. He showed you how much spices, how long to bake all, how to properly cut everything, all that stuff.

Felix:

He spat it right out. He wasn't swallowing that! When you gave disapproving eyes he argued he can't do that to his body. He told you to go follow a cooking class before you start offering food to people. So he didn't touch any of your food again until you learned from someone who can do it excellently.

Sylvain:

A lot of "euhm, okay, that..." as he was deciding how to word it kindly. He assured you there's potential here so let's explore it. So he took you to the kitchens and showed you how to properly make it. Afterwards both ate it, chuckling about how much better it is and that you can now make it properly.

Ashe:

When the food touched his taste buds his whole body did a weird jerk reaction to it. It was genuine surprise. When you asked how it tastes he froze then slowly said it could use some adjustments. So next time you cooked it he was there, using the excuse he'll do the dishes as you are cooking, and quickly intercepted before you could ruin the meal.

Ingrid:

She almost spat it out so she quickly covered her mouth. Took all courage to swallow it then force a smile. This food was a crime to food! Slowly she told you that it was fine but maybe can adjust a few things about it then began making suggestions on how you could perfect this meal.

Mercedes:

An 'oh dear' came out, having difficulty swallowing it down. Once it was down she nervously admitted she can't eat that then told you what she finds not pleasant about it. She quickly assured you maybe it's just her preferences so don't take it to heart.

Annette:

She loves to cook but it always ends up in a mess. So when she tasted your food she knew a solution! Both began cooking together from now on: with her instructing you and you handling the cutting and cooking so finally messes and somehow explosions weren't an issue anymore.
