Sourdough Strawberry Shortcake

Sourdough strawberry shortcake is both delicious and incredibly simple to make without spending hours in the kitchen!

Begin by grating the butter using a cheese grater, placing it into a large mixing bowl. Add the flour and use a bench scraper or fork to cut the butter into the flour until it resembles small, pea-sized crumbles.
Add the sourdough starter discard, heavy cream, and sugar to the mixture, stirring thoroughly with a stiff spatula until fully combined. Cover the bowl and allow it to rise on the counter at room temperature for 10-12 hours.

Preheat the oven to 400°F (204°C). In a small bowl, combine the salt, baking soda, and baking powder, using a fork to ensure there are no lumps. Sprinkle half of this mixture over the dough and use your hands to incorporate it. Then, sprinkle the second half and continue working it into the dough until it is fully combined.
Prepare your work surface by generously sprinkling it with flour, then transfer the dough onto it. Dust the top of the dough with flour and use your hands to gently press it into a rectangular shape, approximately 1 inch thick. To cut out biscuits, use a biscuit cutter by firmly pressing straight down into the dough and then lifting it straight up. (Twisting the cutter can effectively seal the edges, thereby limiting their rising potential compared to if it is pulled straight upward. You can also use a bench scraper or a sharp knife to cut the dough into squares.)
Arrange the biscuits in a parchment-lined 12" cast iron skillet or baking sheet and bake for 25-30 minutes, or until the tops are golden brown. Remove and allow to cool.

Place the heavy cream, vanilla extract, and powdered sugar into a large mixing bowl. Use an electric hand mixer to beat the mixture at high speed until it forms stiff peaks. Transfer the whipped cream to the fridge until you are ready to assemble.

Wash the strawberries, remove the stems, and cut them into quarters. Toss them with sugar and lemon juice in a bowl and transfer the bowl to the fridge until you are ready to assemble.
