This is news to me!

Who can resist a plate of flawlessly crispy roast potatoes, their exteriors bathed in golden crunchiness while their insides remain soft and tender? Yet, reaching such culinary excellence often proves elusive. Throughout the years, I’ve embarked on a multitude of trials to perfect my roast potatoes, but none have ever eclipsed the technique guarded by my nana. At family feasts, her roast potatoes always held an unmatched prestige, complementing any main dish with ease. What is it that elevates her potatoes above all others? Let’s delve into the time-honored secrets behind nana’s exceptional roast potatoes.

The Quintessential Ingredient Nana Holds Dear

The enchantment woven into nana’s roast potatoes centers on a singular, almost surprising component: semolina. After endless rounds of refinement, she unearthed that this modest grain gives rise to a remarkable crispiness when deployed with precision. It’s the unique crunch imparted by semolina that sets her potatoes apart, crafting a texture that goes beyond the ordinary.

Unveiling the Alchemy of Crispness

Culinary crispiness is grounded in a symphony of chemical reactions. As potatoes roast, their outer layers undergo intense heat exposure, triggering the Maillard reaction—a process where amino acids and sugars forge that coveted, golden-brown crust. Semolina takes this a step further by drawing out moisture and forming a textured exterior, amplifying the crunch while preserving the creamy core.

Choosing the Prime Potatoes for Roasting

To craft the quintessential roast potato, you must begin with the optimal variety. Nana’s preference always falls upon floury potatoes like Russets or Maris Piper, thanks to their elevated starch levels which lend to an airy, fluffy interior. Their robust skins, once agitated, provide the perfect canvas for cultivating crispness.

The Craft of Preparation for Maximum Crunch

Preparation is pivotal when aiming for that coveted crunch. Nana meticulously peels and segments the potatoes into uniform pieces, ensuring even cooking throughout. She then briefly parboils them, a crucial step in softening the edges to better absorb the semolina. Once drained, shaking the potatoes vigorously in the pan creates roughened edges that are vital for achieving crisp perfection.

Mastering the Roast: A Step-by-Step Ritual

Begin by preheating your oven to a searing 220°C (428°F), allowing the roasting pan to heat within. While waiting, gently coat your parboiled potatoes with a few tablespoons of semolina, making sure each piece is evenly dusted. Retrieve the blistering pan from the oven, pour in a generous portion of oil or duck fat, and arrange the potatoes with enough breathing space to avoid crowding. Roast them for roughly an hour, turning midway, until they reach a perfect golden crisp.

Experimenting with Alternate Coatings

Though semolina remains nana’s preferred choice, other adventurous souls have experimented with polenta or cornmeal for similar outcomes. Each introduces a distinct texture and flavor, but the overarching principle stays the same: to create a moisture-absorbing layer that enhances crispiness. Yet, semolina’s finer texture often reigns supreme for achieving an even coating and superior crunch.

Pitfalls to Sidestep

Common missteps include overcrowding the roasting pan, which steams rather than roasts the potatoes. Additionally, neglecting to sufficiently preheat the oil may result in uneven browning. Skipping the parboil phase will deprive the potatoes of the soft centers we all crave.

Nana’s Tried-and-True Tips for Flawless Potatoes

Nana is a staunch advocate of patience: parboiling the potatoes thoroughly and allowing ample time for roasting. She emphasizes using high-quality oils or fats to enrich the flavor. Another tip? Let the semolina-coated potatoes rest briefly before roasting to help develop a more uniform crust.

Serving Ideas and Perfect Pairings

These divine crispy roast potatoes are incredibly versatile, harmonizing beautifully with roast meats like beef or chicken. They also pair splendidly with velvety gravies and roasted veggies. For a final flourish, dust them with coarse sea salt and a sprinkle of fresh rosemary just before serving.
