My soup base is exactly the same for all of my soups which guarantees that legit all of them taste like heaven. There is a magic ingredient in there that you can only get in Germany but I found the next best thing and linked it for you guys!
2 cloves of garlic
1 tsp olive oil
"Theme ingredient": Carrot, pumpkin, potato, celery root, potato etc whatever you have available (or in season if you are shopping on budget)
Magic ingredient: Dried veggie stock
Pepper to taste
Tip: I add a little potato to almost all of the blended soup recipes for a little more creaminess and body.
