Masala Dosa with Spiced Potato Filling

The queen of South Indian breakfasts, a game of patience. The secret to the crispy, paper-thin crepe is fermentation: the rice and lentil mix rests overnight, coming alive with bubbles. This gives the batter its airy, tangy, crispy texture, a perfect contrast to the soft, spiced potato filling inside.

Instructions

1

Day before: Wash rice and dal separately. Soak in plenty of water for 4-6 hours. Add fenugreek seeds to rice.

Tip: Fenugreek aids fermentation and gives a nice brown color.
2

Grind dal with little water to fluffy paste. Transfer to bowl. Grind rice (can be slightly coarse), mix with dal. Add salt, mix with HANDS.

Tip: Mixing by hand introduces wild yeast/bacteria from skin aiding fermentation. Fluffy texture comes from air bubbles.
3

Cover and ferment in warm place 8-12 hours until doubled and smelling sour.

Tip: CO2 gas rises the batter, lactic acid gives flavor.
4

Filling: Boil potatoes, peel, mash roughly. Heat oil, pop mustard seeds. Add curry leaves, chopped chili, diced onion.

Tip: Mustard seeds must pop to release flavor.
5

Sauté onion until translucent, add turmeric, then potatoes and salt. Splash water if dry. Set aside.

Tip: Turmeric is fat soluble; oil brings out its color.
6

Cooking: Heat skillet to medium. Sprinkle water; if it sizzles and evaporates instantly, heat is right. Wipe dry.

Tip: Leidenfrost effect indicates correct temp.
7

Pour ladle of batter in center, spread in spiral motion outwards thinly with bottom of ladle.

Tip: Be quick, thin batter sets fast.
8

Drizzle oil/ghee around edges. Cook until bottom is golden brown and edges curl.

Tip: Fat helps crisping.
9

Place potato filling in center, fold, and serve immediately.

Tip: Steam softens it quickly, so eat fresh!

Recipe FAQ

Why does dosa stick?
Pan wasn't hot enough or not seasoned well. Rub with an onion and oil before cooking.
Why isn't it crispy?
Batter too thick or not fermented enough.
Leftover batter?
Keeps in fridge 2-3 days; gets tangier and better.
