Food safety when tasting from dish
You don't really need a lot of tasting spoons, just one. Use your stirring spoon to pour some into your tasting spoon without touching. Or if that's too tricky, serve a bit onto a small plate/bowl.

But if you're just cooking for yourself I personally wouldn't really worry about it, because in general you'll be cooking the food at a safe temperature, not just above the danger zone (140F/60C) but something safe for all meat (180F/80C) so whatever bacteria you put in with your spoon is just going to get killed. We routinely put potentially contaminated things like raw meat into our food while cooking, and let the heat take care of it; whatever you might be carrying isn't any more dangerous.
