Shades of autumn, turning to winter. Orange squash, the vibrant color of fallen leaves. Fried sage leaves, brittle and buttery brown. Tart dough in the oven, garlic oil brushed on golden, a tangle of caramelized onions. We swoon.

We had our neighbors over into the test kitchen the other day. The Empire Grade Purveyors, aka Daniel and Zhanara Gallegos, live just down the road a ways from the test kitchen, and they’re just the kind of neighbors we like to connect with. Their joint venture as the Empire Grade Purveyors focuses on the intersection of food, community, and art. It’s the food we were mostly concerned with, on this day, as we made this exquisite seasonal tart, but as we have discovered so many times before, food is a perfect vehicle for connection and community. And art is everywhere, isn't it? In the glow of fresh ingredients, in the practice of attention and thoughtful action, in the depiction of even the most ordinary moments.
The discussion was wide-ranging. The tart melted in the mouth. Outside the sun shone down in unseasonal golden rays. We cut another slice. Oh, just another sliver. Golden.

For those in the area, the Empire Grade Purveyors provide regular access to their incredible wood-fired breads and pastries by pick up, along with occasional pop-up events and catering. You can check them out online at

The recipe below comes in two parts; the tart dough, which makes enough dough for four tarts, and the filling itself, which can vary with the seasons. “I like to work in this scale, “ Daniel remarks, as he begins to mix the dough. “You can do everything by hand. And you always have extra for friends and family, or the freezer.”
We like it, too.
Thanks again, Purveyors.
