To achieve the perfect crumb, be sure to use cold butter and take care not to overwork the dough.
Preparation Method
Preheat the oven to 350°F on Convection Mode with a rack set on position 3.
Whisk together all the dry ingredients and the thyme.
Mix the butter into the dry ingredients by hand until hazelnut-size pieces form.
Add in cheese and then the heavy cream.
Mix gently by hand until the dough comes together. This can also be done in a stand mixer or food processor, though take caution not to overwork the dough.
Turn out the dough onto a floured surface and press out into a 7-inch disk, about 1 inch thick.
Cut disk into eight wedges.
Place on a parchment lined baking pan and bake for 16–18 minutes until golden brown around the edges.
