You don't have to cook fancy or complicated masterpieces — just good food from fresh ingredients.
Julia Child

Cooking is at once child's play and adult joy. And cooking done with care is an act of love.
Craig Claiborne
NYT Food Editor

James Beard
Culinary Pioneer
Salt is the only rock we eat. Everything else you do to food is secondary.
Samin Nosrat

A recipe has no soul. You as the cook must bring soul to the recipe.
Thomas Keller
Chef-Owner, Per Se & The French Laundry
The more you know, the more you can create. There's no end to imagination in the kitchen.
