^ Starch? NEVER. (It just congeals into goop.) I had a gravy wars thread on TV that was going well until I got banned. Sigh. Maybe it was because I called makers of gravy who use Bisto poofie hooligan short order cooks. Or something to that effect.
You can make gravy out of any meat, be it roasted, braised or pan-fried.
Cook the meat and then slap the roaster, pot or pan on the stove over pretty high heat so it's bubbling. Sprinkle FLOUR into the drippings to make a "roux". You have to stir constantly with a fork to ensure it doesn't go lumpy; alternatively, you can mix flour with COLD water and add it to the drippings in a slow steady stream while also stirring constantly. I never measure, Hootad, but start with a few tablespoons of flour for a roast or a turkey. If there are lots of drippings, add a bit more. Brown the flour (a few minutes or five) and then add some HOT water or broth and keep stirring. If you boiled potatoes, always use that HOT water for the broth. Stir, stir, stir is the key factor. If it's too thin, cook it longer; if it's too thick, add more HOT liquid. Taste and add salt and pepper accordingly.
You can also make milk gravy, but I reckon you need a gravy for your Canadian Thanksgiving dinner this Sunday.
Use the spud water. Get somebody to keep stirring the gravy while you serve up everything else.
Always save the leftover gravy; add cut up meat, boil gently and pour over bread or mashed spuds. Yummy.
