If you’ve ever made homemade tortillas, tamales, or other Mexican dishes, you’ve likely come across masa, a dough made from corn treated with lime. It is a staple in Mexican cuisine and is used in various dishes, but how long does it last?
If you purchase fresh masa or make it yourself, it should be used within two to three days. However, if you’ve purchased masa harina, a dried masa flour, it can last up to 9-12 months if stored properly. After this time, they should be discarded due to deterioration.
To ensure your masa harina stays fresh, store it in an airtight container in a cool, dry place away from direct sunlight. Once mixed with water, it should be stored in the refrigerator for up to 3 days.
What is Corn Masa?
If you’re a fan of Mexican cuisine, you’ve probably heard the term “corn masa” before. But what exactly is it? It is a dough made from dried corn kernels cooked and soaked in an alkaline solution, typically lime water.
This process, known as nixtamalization, helps to break down the tough outer layer of the corn and make it more digestible.
This is a staple ingredient in many traditional Mexican dishes, including tortillas, tamales, and pupusas. It’s also used in various Latin American and Caribbean cuisines.
There are two main types of corn masa: masa harina and fresh masa.
Masa harina is a type of corn flour that’s made from dried masa. It’s commonly used to make tortillas and other dishes requiring fine-textured dough.
On the other hand, a fresh one is made from freshly prepared flour and has a coarser texture. It’s often used to make tamales and other dishes requiring thicker dough.
How Long Does Masa Last?
If you have masa leftover from making tamales or other Mexican dishes, you may wonder how long it will last. Here’s what you need to know:
- Refrigerated masa: If you have a refrigerated one, it should last for up to a week in the fridge. Store it in an airtight container to prevent it from drying out.
- Frozen: If you have frozen masa, it can last up to six months in the freezer. Again, store it in an airtight container to prevent freezer burn.
- Cooked: If you have cooked masa, it will last up to three days in the fridge. You can also freeze the cooked one for up to six months.
It’s important to note that masa will dry out over time, so it’s best to use it as soon as possible. If you notice that it is starting to dry out, you can add a little bit of water to it to moisten it up.
Generally, making only as much masa as you need for a particular recipe is best. This way, you can avoid having leftover masa that you may not be able to use before it goes bad.
How is Masa Prepared?
It is a traditional dough used in many Mexican dishes, including tortillas, tamales, and pupusas. It is made from masa harina, which is a type of corn flour that has been treated with lime. Here’s how you can prepare it at home:
- 2 cups masa harina
- 1 1/2 cups warm water
- 1/2 teaspoon salt
- In a large mixing bowl, combine the corn flour and salt.
- Slowly add the warm water while stirring with a wooden spoon until the dough comes together.
- Knead the dough for 5-10 minutes until it becomes smooth and pliable.
- Let the dough rest for 30 minutes before using it.
How to Store?
It can be stored in the refrigerator for up to 3 days or in the freezer for up to 6 months. Here are some tips for storing:
- Wrap it tightly in plastic wrap or aluminum foil.
- Label the package with the date of preparation.
- Store the masa in an airtight container to prevent it from drying out.
- If it becomes dry, add a little warm water and knead it again until it becomes pliable.
How to Tell if Masa Has Gone Bad?
It can be difficult to see if it has gone bad just by looking at it. Here are a few things to look out for to determine the quality:
- Smell: It has likely gone bad if it has a sour or rancid odor. Fresh ones should have a slightly sweet, corn-like smell.
- Texture: It deteriorates if your masa feels slimy or has a sticky texture. The fresh dough should have a smooth, slightly grainy texture.
- Color: Masa that has gone bad may have a gray or brownish tint, whereas fresh one should be bright white or yellow.
- Taste: It has gone bad if it tastes off or has a bitter flavor. The fresh dough should have a slightly sweet, corn-like taste.
Keep it refrigerated in an airtight container to prevent spoiling too quickly. If you’re unsure about the quality, it’s better to err on caution and throw it out.
Can You Freeze Masa for Tamales?
Yes, you can freeze it for tamales. Freezing is a great way to extend its shelf life. To freeze it, wrap it tightly in plastic or aluminum foil, then place it in a freezer bag. Be sure to label the bag with the date to know when you froze it.
When ready to use, thaw it in the refrigerator overnight. Once it’s thawed, you can use it just like the fresh one.
How Long Does Corn Flour Last?
Masa flour is made from corn flour, so knowing how long it lasts is essential. Corn flour can last up to 6 months in the pantry if stored in an airtight container. However, it’s best to use it within 3 months for optimal freshness.
Always check the best-before date on the bags of corn flour. Don’t store it in the fridge, as it can absorb moisture easily. If you find that your corn flour is infested, discard it and check in your pantry for any signs of bugs or eggs. Clean it properly before storing the food items again.
