Lye Water (Lihiya): What it is and How to Use it in Filipino Cooking

If you've ever made kutsinta or pichi-pichi and noticed that chewy, slightly springy texture, there's a good chance lye water had something to do with it.

In Filipino cooking, lye water is a small but powerful ingredient used in many traditional rice cakes (kakanin). It changes the texture and even the color of certain desserts.

But what exactly is it? Is it safe? And how do you use it properly?

Let's break it down in simple terms.

What is Lye Water?

Lye water (called lihiya or lihia) is a clear, alkaline liquid used in small amounts in cooking. In Filipino kitchens, it's mostly added to rice cakes to make them chewier and slightly darker in color.

It's made from sodium hydroxide or potassium hydroxide mixed with water. That might sound intimidating, but when used correctly and in very small amounts, it's considered safe for food.

You might also hear about kansui, an alkaline solution used in making ramen noodles. While it works in a similar way - changing texture and color - kansui is typically used for noodles, while lye water (lihiya) is more common in Filipino rice cakes.

What Does Lye Water Do in Filipino Cooking?

In Filipino cooking, lye water is mainly used to change the texture and color of certain desserts.

Because it's alkaline, it reacts with starches in rice or cassava and makes them firmer and chewier. That's why desserts like kutsinta have that slightly springy, sticky bite instead of being soft or crumbly.

It can also affect color. In some recipes, lye water helps give rice cakes a darker or slightly yellow color.

You only need a small amount - usually just a teaspoon or less. Too much can make the texture unpleasant and leave a bitter taste, so it's important to measure carefully.

Is Lye Water Safe to Use?

Yes, when labeled food-grade and used in very small amounts, lye water is safe for cooking.

In Filipino recipes, you typically only use a small amount - just enough to help change the texture of rice cakes like kutsinta or suman sa lihiya.

When measured properly and mixed with other ingredients, it's safe to eat.

The key is to use only food-grade lye water, measure carefully, and follow the recipe exactly.

Using too much can make food taste bitter and affect the texture. Like many ingredients, it works well when used correctly - but more is not better.

Where to Buy Lye Water

You can usually find lye water (lihiya) at Asian or Filipino grocery stores. It's typically sold in small bottles and labeled as food-grade.

If you don't have an Asian market nearby, you can also find food-grade lye water online. Just make sure the label clearly says it's safe for cooking.

Avoid industrial or cleaning-grade lye. Those are not meant for food use.

Because you only use small amounts in recipes, one small bottle can last a long time.

Can You Substitute Lye Water?

If you can't find lye water, you can try using baked baking soda - but it's not exactly the same.

When you bake baking soda in the oven, it becomes more alkaline. That helps a little with texture, but it won't give you the same chewiness or color you get from real lye water.

For desserts like kutsinta or suman sa lihiya, lye water really does make a difference.

Some people use baked baking soda as a substitute. It makes the mixture slightly more alkaline, which can help with texture. But it's milder and won't give you the same chewiness or color as real lye water.

Filipino Recipes That Use Lye Water

Lye water (lihiya) is commonly used in traditional Filipino rice cakes to create that signature chewy texture. Here are some popular examples:

• Kutsinta: Steamed rice cake topped with grated or toasted coconut, yema, or cheese. A traditional kutsinta version is made in a pan with two layers-a firmer bottom and a softer top.
• Suman sa lihiya: Glutinous rice wrapped in banana leaves, topped with latik.
• Pichi-pichi: Steamed cassava cakes topped with grated coconut or cheese.
