If you’ve got a spare potato or two, this is the gold standard. Just boil another potato (or a few small ones), mash it separately, and fold it into your runny mixture. Instant rescue, no extra drama needed.
But what if your pantry is bare? Don’t you dare give up—life is too short for surrender!
Enter the Kitchen Heroes
Grab a strainer or a clean kitchen towel. Pour the potatoes in and gently press out the excess liquid. You’re not squeezing them dry—just removing the extra moisture. Boom—you’ve got a thicker mash with zero added ingredients.
Or, try instant potato flakes. Yes, the ones from a box. Stir in a tablespoon at a time and watch the magic happen. No shame in that game—it’s just practical wizardry!
