When a recipe calls for adding oil, garlic, and onions to a pan, always add garlic last. This keeps it from burning and tasting bitter.
Make your own celery flakes. Just cut and wash the leaves from the celery stalks; place them in the oven on low heat or in the hot sun until thoroughly dry. Crumble and store in an air-tight container.
