Hi, I’m Savannah Brooks, 35 years old, born in Charleston, South Carolina, and now living in Seattle, Washington. My kitchen is small but full of life shelves stacked with spices from all over the world, a sourdough starter that feels like part of the family, and usually a pot bubbling away with something hearty and comforting.

Food has always been the center of my world. Growing up in Charleston, I was surrounded by Southern cooking shrimp and grits, okra stews, biscuits that could melt in your mouth. My grandmother was the first person who showed me that recipes are more than instructions they’re stories passed from one hand to another. I still keep her stained recipe cards in a box, though I’ve long since memorized every one.

My path wasn’t traditional. I studied journalism first, thinking I’d write stories for a living. And I do but now I write them on the plate. After years of working late nights in small cafés, catering weddings, and even running a food truck, I found my true rhythm in cooking that bridges my Southern roots with global inspiration. These days, you’ll find me folding lemongrass into chicken soup, adding harissa to cornbread batter, or topping fried green tomatoes with a touch of miso.

I don’t believe cooking is about perfection it’s about connection. My kitchen is a place for experiments, happy accidents, and plenty of laughter. I’ve burned cookies, curdled sauces, and dropped more than one cake. But every mistake taught me something, and every shared meal reminded me why I love this work.

I cook for people who want food that feels like home but isn’t afraid to wander a little. My hope is that when someone takes a bite of my food, they feel cared for, seen, and maybe a little inspired to try something new in their own kitchen.

So, welcome to my world where Southern comfort meets global curiosity, and every dish tells a story.
