Makes 6 tartlets  

Our gluten-free tart crust has the subtle taste of almonds and fresh herbs, and it can be filled with just about anything. One of our favorites is this clove-spiced spinach and mushroom filling. Potato starch, tapioca starch, and all flours are available from Bob’s Red Mill.

Tartlet shells½ cup superfine chickpea flour or garbanzo bean flour¼ cup almond flour or almond meal2 Tbsp. potato starch, tapioca starch, or cornstarch½ tsp. sea saltFreshly ground black pepper1 Tbsp. each finely chopped fresh rosemary and thyme3 Tbsp. virgin coconut oil plus more for pans

Filling2 Tbsp. virgin coconut oil or olive oil (for frying)
1 small red onion, finely chopped
½ tsp. ground cloves
4 cups fresh spinach
1 leek, thinly sliced (including green leaves)
12–15 crimini (baby bella) mushrooms, sliced
Juice of ½ lemon

special equipment: Six small tartlet pans

Making the Tartlet shells: Combine the first 4 ingredients in a bowl; season with salt and pepper. Add coconut oil and 3 Tbsp. ice-cold water. Using your hands, work dry ingredients toward the center until dough forms. Gather dough into a ball, wrap in plastic, and chill for 30 minutes. DO AHEAD: Dough may be made 1 day ahead. Wrap tightly with plastic and chill.

Preheat oven to 375°. Divide dough evenly into 6 portions. Form each portion into a ball and press 1 dough ball evenly onto bottom and up sides of each tartlet pan. Trim dough flush with edge of pans. Prick bottom with a fork to prevent it from bubbling as it bakes. Bake until golden, about 15 minutes.

Let tartlet shells cool slightly, then invert each pan and turn out shells onto a wire rack and let cool completely.

Making the filling  Heat oil in a large skillet over medium heat. Add onion and cloves and cook until onion is lightly browned; add spinach, leek and mushrooms. Cook until spinach is brightly colored, 3–5 minutes. Add lemon juice and cook 2 minutes longer. Spoon 2 dollops filling into each tartlet shell and serve hot.
