What is three fourth teaspoons?

Use a half teaspoon measure once, fill it to rounded and using a knife or metal spatula level the baking powder off. Place this into your recipe and repeat the procedure using a one-quarter teaspoon measure. You may also use your 1/4 tsp three times. You can purchase a set of graduated measuring spoons from most kitchen "gadget" shops or in the grocery store.

Do NOT use a teaspoon from your regular flatware set. Always level off the ingredients for a correct measure and to avoid problems with your recipe.
