At first glance, rice flour sounds pretty straightforward—it’s flour made from rice, right? But in reality, there’s a bit more to it. Whether you’re making pupusas, mochi, tortillas, or gluten-free baked goods, understanding what rice flour really is—and how it’s made—can make a big difference in your recipes.
In this post, we’ll break down what rice flour is, how it differs from simply grinding rice at home, and the key differences between types of rice flour you’ll find in stores or use in traditional Salvadoran cooking.
🍚 So, Is Rice Flour Just Ground-Up Rice?
Technically, yes—but there’s nuance.
Rice flour is made by finely grinding rice grains into a powder. But how it’s prepared, what kind of rice is used, and whether it’s raw or soaked first changes its texture, behavior in cooking, and how it interacts with water, oil, and heat.
There are two main ways to get rice flour:
1. Commercial Rice Flour (Dry-Milled)
- Made from raw, dry rice
- Ground into a fine powder using industrial mills
- Often labeled as white rice flour or brown rice flour
2. Traditional Homemade Rice Flour (Wet-Milled)
- Rice is soaked first, then ground while damp
- Sometimes cooked or parboiled slightly, then dried
- Results in a softer, more elastic flour
- Common in Salvadoran rice pupusas and Asian rice cakes
So while rice flour is “ground-up rice,” how and when it’s ground matters a lot.
🔬 How Is Rice Flour Made?
Homemade Method:
- Soak rice in water (6–12 hours)
- Drain and rinse
- Blend or grind until smooth and pasty
- Use immediately or dry into powder form
This method produces a wet flour ideal for soft doughs like pupusas de arroz or tamales.
Industrial Method:
- Use dried rice kernels
- Grind using stone mills or hammer mills
- Sift for uniform texture
- Package and sell as dry flour
This is what you’ll find in most grocery stores under brands like Bob’s Red Mill, Erawan, or King Arthur.
🍽️ Types of Rice Flour and How They’re Used
| Type | Texture | Use Case |
|---|---|---|
| White Rice Flour | Fine, soft | Baking, tortillas, pupusas, thickening sauces |
| Brown Rice Flour | Slightly gritty | Gluten-free breads, muffins, pancakes |
| Sweet/Glutinous Rice Flour | Sticky, smooth | Mochi, dumplings, sticky cakes |
| Homemade Wet-Milled | Soft, stretchy | Pupusas de arroz, tamales, steamed cakes |
✅ Note: “Glutinous” rice flour contains no gluten—it’s just extra sticky!
🧠 Common Misconceptions
❌ Myth: “You can just blend rice in a blender and call it flour.”
Not quite. While you can grind dry rice at home in a high-powered blender or spice grinder, it will:
- Be coarser
- Not behave like finely milled flour
- Affect texture in delicate recipes like pupusas or pancakes
For best results, sift your flour or invest in a fine grain mill if making a lot.
🥘 What Happens If You Use the Wrong Rice Flour?
In recipes like rice pupusas, tamales, or empanadas, using the wrong type of rice flour can lead to:
- Dough that cracks or crumbles
- Tough or dry texture
- Dough that won’t hold fillings well
Always check what the recipe calls for: wet-milled vs. dry-milled, white vs. glutinous, etc.
🧂 How to Store Rice Flour
- Dry flour: Airtight container, cool and dry place. Use within 6 months
- Homemade wet flour: Refrigerate and use within 3 days or freeze in portions
- Vacuum-sealed store flour: Check expiration and refrigerate after opening
🧁 Can You Use Rice Flour Instead of Wheat Flour?
Yes—for many recipes, especially in gluten-free baking. However:
- It behaves differently from wheat flour
- No gluten = different elasticity and structure
- You’ll often need binders like xanthan gum or blend with starches (like tapioca or potato starch)
