Try arrowroot powder for making killer gravy.
It works the same as flour but doesn’t leave the gravy tasting pasty like flour does.
For the record, arrowroot is gluten free and is a terrific thickening agent you can use in more than gravy.
If your gravy made with flour tastes pasty you are doing it wrong. Equal amounts fat and flour by weight. Melt the fat (I like butter) Stir in the flour and cook for a few minutes. Cooking the flour eliminates the pastiness.

Thanks, my dear, I’ll give it a go!
If the flour is making the gravy taste pasty, it needs cooked longer before adding the liquid.
