HOW TO MAKE BUTTERMILK SUBSTITUTION RECIPES

Steps:

• Combine the milk or cream and acid. Stir the milk or cream and lemon juice or vinegar together in a measuring cup.
• Let stand 5 to 10 minutes. Let the mixture stand at room temperature for 5 to 10 minutes. When it is ready, the milk will be slightly thickened and you will see small curdled bits. This substitute will not become as thick as regular buttermilk, but you will also not notice the curdled bits in your finished recipe.
• Use the buttermilk. Use this substitute (including curdled bits) as you would buttermilk in your recipe.

Steps:

• Heat oven to 425 degrees. In a medium bowl, use a fork or a wooden spoon to mash together the goat cheese, egg, garlic, tarragon, lemon zest, salt and nutmeg until smooth. Switch to a whisk and beat in the crème fraîche until smooth.
• On a lightly floured surface, roll out puff pastry into a 13-by-11-inch rectangle about 1/8-inch thick. Transfer the dough to a parchment-lined cookie sheet. With a sharp knife, lightly score a 1/2-inch border around the edges of the puff pastry.
• Spread the crème fraîche mixture evenly inside the scored border. Line up the asparagus spears on top, and brush them with olive oil. Sprinkle some salt and the grated Parmesan over the asparagus.
• Bake until the pastry is puffed and golden, 25 to 30 minutes. Let it cool on the cookie sheet for at least 15 minutes or up to 4 hours before serving. Then sprinkle black pepper, red-pepper flakes (if using), the shaved Parmesan and tarragon leaves. Drizzle a little oil on top.
