On one hand, we have the flour fanatics, who swear by the almighty power of wheat to thicken their soups. And, let's be real, it's a solid choice – after all, who doesn't love a good bread based thickening agent? But, beware, my friends, for lumps are lurking around every corner, just waiting to ruin your perfectly good soup.
Now, you might be thinking, "But what about all-purpose flour?" Well, let me tell you, it's a jack-of-all-trades, but master of none. It'll get the job done, but don't expect any miracles. And, if you're feeling fancy, you can always whip up a roux –just be prepared to stir like your life depends on it.
