Why it works: Rice and potato match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 851 recipes. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓

Ingredients
Directions
Prepare
Soak the rice for a few hours in hot water and some salt before cooking.
Peel the potatoes and slice them in a round shape. Optionally use unpeeled potatoes.
In a medium-sized pot, fill it halfway with water and bring the water to a boil.
Parboil the rice
Add the rice (and the water it was soaking in) and let it cook for a few minutes until it starts boiling.
Occasionally pick a few rice grains with a spoon and chew on them to see if they have softened.
When the rice is half-crunchy half-soft, take it out and drain it in a kitchen strainer.
Run tap water over the rice to wash out some of the salt.
Layer and steam
Pour the oil into the pot and add 4 ounces of water.
Lay the potatoes in the bottom of the pot.
Add a bit of salt to the potatoes.
Pile the rice loosely in the shape of a mountain on top of the potatoes.
With the back of a spoon, make five holes, one in the center and four around it, so that the rice can breathe during cooking.
Spread a little water on top and close the lid.
Let it cook for a couple of minutes on high heat.
When the rice starts to steam, change the setting to medium heat and let it cook for about 15 minutes.
Then turn the heat to medium-low, sprinkle some cooking oil to stop it from drying, and let it cook for another 10 minutes.
Nutrition, whole recipe (rough)
Counts 4 of 5 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 4 portions
| Ingredient | Portion assumed | kcal |
|---|---|---|
| Rice | 1 cup cooked (158g) white | 206 |
| Potato | 1 medium (173g) baked | 161 |
| Olive Oil | 1 tbsp (14g) | 119 |
| Salt | 1 tsp (6g) | 0 |
| Water | not in our table | 0 |

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White long grain rice
- Forms the fluffy body of the dish and, once crisped at the base, the golden crust.
- Cooking oil
- Fries the bottom layer of rice to a crisp and keeps the top from drying out.
- Potatoes
- Form a golden, crisp layer under the rice that browns in the hot oil.
The step that matters
Parboiling the rice until half-crunchy half-soft. Rice that is cooked through before layering turns mushy when steamed. Stopping at a firm centre lets it finish gently in steam and oil, keeping the grains separate.
