Masa Harina

What Is Masa Harina?

Masa harina is a special Mexican corn flour obtained by cooking and soaking corn kernels in water containing slaked lime (calcium hydroxide) — a process called nixtamalization — then washing, grinding, and drying them. Its name means "dough flour" in Spanish.

Nixtamalization gives the corn a distinctive flavor and the ability to form dough; that is why masa harina, unlike ordinary corn flour, forms a pliable dough (masa) when kneaded with water. It is the staple ingredient of corn tortillas and tamales; it is gluten-free.

Nutritional Values of Masa Harina

Masa harina is a corn flour providing about 365 kcal per 100 grams, consisting mainly of carbohydrate; due to the lime treatment, it also carries some calcium and is gluten-free. Values vary by brand; they are approximate.

How Should Masa Harina Be Used?

Masa harina is kneaded with water (and salt) to form a pliable dough; this dough is shaped and cooked into tortillas, tamales, and similar dishes. Being gluten-free, it is also suitable for people with gluten sensitivity; it is not a direct substitute for ordinary corn flour.

This information is general; masa harina is a food, not a substitute for medical treatment.

How to Choose Masa Harina?

Good masa harina is dry, lump-free, has a fresh corn smell, and is labeled as "masa/nixtamal." It should not be confused with ordinary corn flour or cornstarch; products that are damp or have a rancid smell are not preferred.

• Should be dry and lump-free
• Should be labeled "masa/nixtamal"
• Should not be confused with ordinary corn flour

How Is Masa Harina Stored?

Masa harina is stored in a sealed container, in a cool, dry, and dark place; moisture causes clumping and spoilage. The refrigerator or freezer can be preferred for long-term storage.

Using Masa Harina in the Kitchen

Masa harina is used most in corn tortillas, tamales, gorditas, pupusas, and thickening some soups and stews. It is kneaded into dough with water and shaped by pressing or rolling; it is cooked on a griddle/pan.

What Is the Difference Between Masa Harina and Corn Flour?

Ordinary corn flour is ground raw corn; masa harina is made from corn processed with lime (nixtamalized) and can form dough. This is why ordinary corn flour cannot replace masa for tortillas.

Frequently Asked Questions

Is masa harina gluten-free?

Yes; being made from corn, it is naturally gluten-free. Sensitive people should check the label against cross-contamination risk.

What can be used instead of masa harina?

There is no exact substitute for authentic tortillas; ordinary corn flour or cornstarch will not give masa's dough-forming property. If unavailable, ready-made corn tortillas can be an alternative.

Why is masa dough elastic?

Nixtamalization changes the corn's structure, making its starch bond more easily with water; this gives masa harina a dough-forming (elastic) property that ordinary corn flour lacks.
