White Potato (Papa Blanca)

White potato (Solanum tuberosum) is the workhorse of the home kitchen—a medium-starch tuber with thin, light-brown skin and white-to-cream flesh that has fed civilizations for over 8,000 years in the Andes before becoming a global staple. Unlike high-starch russets, which excel at baking but fall apart in liquid, or waxy new potatoes that hold their shape even when overcooked, white potatoes occupy a productive middle ground: their 15–17% starch content gives them enough body to mash smoothly without turning gluey, while their firm texture holds up during boiling, roasting, or extended simmering in stews. This versatility is precisely why serious cooks keep a bag on hand. Papa Blanca—the specific Andean variety still common in Peruvian and Latin American cuisine—runs slightly more waxy than commercial American whites and is prized for dishes like causa rellena and locro, but the broader category of white potatoes (including Yukon Gold, Kennebec, and Bintje) covers nearly every kitchen need. The key distinction from russets matters most in specific preparations: white potatoes produce a creamier, more cohesive mashed potato and hold their edges in salads where a russet would crumble, but they lack the fluffy interior a russet develops when baked.
