Here’s a cool trick: if you only have waxy potatoes like reds or fingerlings, you can still win. Boil them, then add a little bit of instant potato flakes (yes, the boxed kind) to boost the starch.
It sounds cheating, but it’s actually science. The flakes absorb excess moisture and mimic that fluffy texture. You’re not replacing the potato—you’re just giving it a backstage pass to greatness.
