Helpful Tips for All Recipes
  • When a recipe call for House Seasoning Blend, you can find the recipe on www.itisakeeper.com. Simply search for "House Seasoning Blend" or you can substitute salt and pepper to taste.  
  • I always use unsalted butter in my recipes.
  • I always use a meat thermometor to test for doneness when cooking meat.
  • When a recipe is made in the oven, it should be pre-heated to the temperature in the recipe, unless otherwise noted.
