First up: cornstarch. This is your superhero in a little box. Mix one tablespoon with two tablespoons of cold water – that’s your slurry. Whisk it into your hot liquid and watch the magic happen. Boom. Thick in about 30 seconds.
But wait! There’s a trap. Don’t dump cornstarch directly into hot soup. You’ll get lumps. Horrible, chalky lumps that will haunt your dreams. Always make the slurry first. Trust me on this.
Then there’s flour. Grandma’s go-to. You’ve got a couple of options here. Make a roux: cook equal parts butter and flour together for a minute, then whisk in your liquid. Or mix flour with a little cold water, just like cornstarch. It works, but it takes a bit longer to cook out the raw taste.
