Potatoes with a high starch content, like Yukon Gold and Russet potatoes, yield fluffy mashed potatoes as their starch expands during the boiling process.
Waxy potatoes, like red and baby potatoes, on the other hand, become gluey, mushy, and unappealing when mashed, as they’re typically watery with a much lower starch content.
If you salt your potatoes post-cooking, you may not get the same saltiness throughout the entire dish. Plus, the dish can turn pasty if you overmix the spuds when adding more salt.
Unlike electric mixers and beaters, which can lead to mushy, goopy potatoes, a hand potato masher or fork gives you more control over your mashed potatoes’ texture.
While high-powered electric mixers quickly break down the starches in potatoes, gentle hand mashing keeps them intact, yielding mashed potatoes with a richer, more robust flavor.
Additionally, when you add cooked, unpeeled potato chunks flesh-side down to the potato ricer, the tool coaxes the potato flesh away from the skin and into your mixing bowl.
When you mash potatoes using a heavy cream with a high fat content, the fats bind to the potato starches, coating every bite with a luxuriously creamy flavor and a silky mouthfeel.
