How to Cook Perfect Rice (Step-by-Step)

1

Rinse the Rice

Rinse rice under cold water until water runs clear (2-3 times). This removes excess starch and prevents mushiness.

2

Measure Rice and Water

Use the calculator above to get exact ratio for your device and grain type. Standard white rice on stovetop: 1:1.5 ratio.

3

Bring to Boil (Stovetop Only)

Combine rice and water in pot. Bring to boil on high heat, then immediately reduce to lowest setting. For rice cookers/Instant Pot, skip this step.

4

Cover and Cook (No Peeking!)

Cover tightly with lid. Do not lift lid or stir. White rice: 15-18 mins. Brown rice: 40-45 mins. Rice cooker/IP handles this automatically.

5

Rest Off Heat

Remove from heat. Keep lid on and let rest 10 minutes. This allows moisture to redistribute evenly.

6

Fluff with Fork

Gently fluff rice with fork to separate grains. Serve immediately or keep warm in rice cooker.

Why Most Rice Recipes Fail

Most failures come from blindly following fixed ratios like "1 cup rice to 2 cups water." In reality, rice cooking is governed by starch structure, surface evaporation, and absorption. Most recipes give you a static ratio but don't account for your specific Device (Stovetop vs Aroma vs Instant Pot) or the specific Grain Variety.

Why Stovetop Rice Fails

Rice cookers are great, but the stovetop method (Absorption Method) is a necessary survival skill. The two biggest mistakes people make are:

  • Peeking: Lifting the lid releases the steam pressure needed to cook the top layer of grains. Trust the timer!
  • Skipping the Rest: The "Rest Step" allows the moisture to redistribute. Without it, the bottom is soggy and the top is dry.

Frequently Asked Questions

What is the rice to water ratio for 1 cup of rice? โ–ผ
For 1 cup of white rice, use 1.5 cups of water on stovetop (1:1.5 ratio). For Aroma rice cooker with standard measuring cup, use 1.33 cups water. For Instant Pot, use 1 cup water (1:1 ratio). Brown rice requires more water: 2-2.25 cups.
How much water for 2 cups of rice? โ–ผ
For 2 cups white rice: Use 3 cups water on stovetop. For Aroma rice cooker: 2.66 cups water. For Instant Pot: 2 cups water. Always rinse rice first to remove excess starch.
What is the Aroma rice cooker water ratio? โ–ผ
If using the Aroma plastic cup (180ml): Fill water to the numbered line inside the pot matching your cups of rice. If using standard US cup: Use 1.33 cups water per 1 cup white rice, or 1.75 cups water per 1 cup brown rice.
How to fix mushy rice? โ–ผ
Drain excess water immediately. Spread rice out in pan, cook on low heat 1-2 minutes to evaporate moisture. Turn off heat, place paper towel under lid, rest 10 minutes. The paper towel absorbs steam. Prevention: Use correct water ratio and never stir while cooking.
How to fix undercooked rice? โ–ผ
Add ยผ cup boiling water evenly over top. Cover tightly with lid (add foil if lid is loose). Cook on low heat or 'Keep Warm' for 5-8 minutes. Do not stirโ€”stirring releases starch and makes rice mushy.
What is the brown rice to water ratio? โ–ผ
Stovetop: 1 cup brown rice to 2.25 cups water. Aroma rice cooker: 1:1.75 ratio. Instant Pot: 1:1.25 ratio. Brown rice takes 40-45 minutes to cook (vs 15-18 for white rice) due to intact bran layer.
What is the sushi rice water ratio? โ–ผ
Sushi rice (short grain) needs less water than long grain: 1:1.25 ratio on stovetop, 1:1.2 in Aroma, 1:1 in Instant Pot. Short grain rice releases more starch, so less water prevents mushiness while maintaining stickiness.
Should I rinse rice before cooking? โ–ผ
Yes, always rinse rice 2-3 times until water runs clear. This removes excess surface starch that causes mushiness and clumping. Exception: Arborio rice for risotto (needs starch for creaminess).
Why does my Instant Pot rice burn? โ–ผ
"Burn" signal means insufficient liquid at bottom or starch buildup. Solutions: (1) Use 1:1 ratio for white rice, (2) Never stir after adding water, (3) Make sure sealing ring is clean, (4) Use "Rice" setting (not "Manual"), (5) Natural release for 10 minutes.
How do I use my Aroma Rice Cooker without the cup? โ–ผ
The Aroma cup is usually 180ml (3/4 of a standard US cup). If you lost it, use a standard measuring cup and our calculator above (select "Aroma"). Generally, for 1 standard cup of white rice, add water to the "Line 1.5" inside the pot, or use 1.33 cups of water.
What's the difference between the Aroma cup and a standard cup? โ–ผ
The clear plastic cup included with Aroma cookers is 180ml (ยพ of a US standard cup). This is why the inner pot lines don't match standard measurements. If you lost the Aroma cup, use our calculator above with "Standard Cups" selected.
Why does brown rice need more water? โ–ผ
Brown rice still has its bran and germ intact. These outer layers are tough and require more water and a significantly longer cooking time to soften.
How much water do I need for 1kg of rice? โ–ผ
For most white rice, use about 2 liters of water for 1kg of rice. Brown rice requires closer to 2.25 liters.
Does short-grain rice need less water? โ–ผ
Yes. Short-grain (Sushi) rice releases more surface starch. It typically needs less water (around 1:1.1 or 1:1.2) than long-grain rice to keep the grains distinct.
