Duck fat is pretty good. Personally I like mustard. Mayo is good but hard to find good mayo that isn't made of soybean oil. Lemon juice can sometimes be really good depending on what it's going on. Salsa is good. Guacamole is good. Bacon makes almost anything taste good. Sometimes just plain old salt and pepper is good. Coconut butter is pretty good. I put it on a sweet potato once and it was delicious. Ketchup is good. I wonder how hard it is to make your own. Spaghetti sauce is good. Cocktail sauce is good. I LOVE tahini ginger sauce. I just bought some pistachio butter at the farmer's market today. Seems like it would make a fabulous pesto, which also reminds me that pesto is good. A lady I know makes pesto out of everything. Not just the traditional basil, garlic and pinenuts. She makes chive pesto, green onion pesto, walnut pesto, spearmint pesto. I love the mint pesto. Wow, that's amazing stuff! I wish I knew how she makes her pestos but I think she just experiments. Which reminds me, olive oil is good. You can get it infused with garlic or herbs, but super strong extra virgin is really tasty. Also, vinegar is good, too. There are various infused vinegars you can get. I once made a tasty salad dressing that was just egg yolk, mustard and vinegar. I bet you could top potatoes or steamed veggies with that nicely. You might try perusing the jarred stuff aisle at Trader Joe's. They always come up with some crazy thing that's worth a try.
So many things to put on your food to make it tasty.
