Just a few tablespoons of butter imparted a strong flavor and light, airy texture. Most recipes that we found called for softened butter and softened cream cheese—a fact that ran contrary to our findings that cold fat produces lighter biscuits. We found that our method yielded better biscuits, so we opted to freeze our butter and cream cheese. Cutting the biscuits into rounds and rerolling the dough created too much gluten and meant that the rerolled biscuits came out tough and leathery.
