The substance will pour out much easier. The product is called Lighter Bake. It is a butter and oil replacement made by Sunsweet. I also found a liquid no fat substitute. It is great for making pie crust.
Roasted peppers are a wonderful thing and easy to make.
Wash the peppers but leave them whole. They may be rubbed with olive oil, but it is not necessary. Place them on a very hot grill, in a grill pan or under the broiler and grill until charred on all sides. Place the hot peppers in a closed plastic bag or under a towel. Cut open the peppers, remove the stem, core and seeds.
