Step 1

Preheat the oven to 425 degrees F (220 degrees C).

Step 2

Line a baking sheet with parchment paper.

Step 3

Whisk together flour, baking powder, baking soda, 1/3 cup white sugar, and salt in a mixing bowl.

Step 4

Cut in cold butter with a knife or pastry blender until the mixture resembles coarse crumbs. (If desired, place flour mixture into the work bowl of a food processor with the butter; pulse several times to cut butter into the flour mixture. Transfer mixture to a mixing bowl, and proceed.)

Step 5

Stir in buttermilk until the flour mixture is moistened.

Step 6

Drop 1/3-cup scoops of the dough 2 inches apart onto the prepared baking sheet.

Step 7

Brush biscuits with heavy cream and sprinkle generously with turbinado sugar.

Step 8

Bake in the preheated oven until golden brown, 15 to 20 minutes.

Step 9

Mix together the sliced strawberries, 1/4 cup white sugar, and lemon juice in a large bowl. Allow berries to rest until juices develop, about 30 minutes.

Step 10

Serve the strawberries with juice over the biscuits.
