Sunagimo (Gizzard) Guide: High-Protein & Healthy Recipes

What is Sunagimo (Gizzard)?

The Biology of the Gizzard

The Second Stomach: Chickens actually have two stomachs; the gizzard is one of them.
The “Teeth” of the Bird: Since chickens don’t have teeth, they use the powerful muscles of the sunagimo to grind up and digest their food.
More Than Just Chicken: While most gizzards found in supermarkets are from chickens, other birds like ducks and turkeys have them as well.
Regional Names: In Japan, specifically in the Kyushu and Tohoku regions, sunagimo is commonly known as sunazuri.

Texture & Flavor Profile

Unique Crunch: Because it is almost entirely muscle with virtually no fat, it has a distinctively firm and “crunchy” texture.
Mild Taste: Unlike liver or heart, which can have a strong iron-like odor or “peculiar” taste, sunagimo is very mild and accessible to most palates.

Culinary Uses: From East to West

Sunagimo is a versatile ingredient enjoyed globally:

In Asia: Often grilled, boiled, or added to soups.
In Japan: A staple of Yakitori, typically seasoned simply with salt, soy sauce, or a mix of sesame oil and salt.
In Western Cuisine: Frequently featured in Ajillo (garlic oil) or prepared as a Confit.

Cooking Tip: Gizzards are thick and can be tough if not handled correctly. For the best results, slice them thinly to ensure they cook through evenly while maintaining that signature crunch.

Health & Nutritional Benefits

Sunagimo is an exceptional choice for health-conscious diners and those on a diet:

High Protein, Low Calorie: Its nutritional profile is comparable to—or even better than—chicken breast for weight management.
Iron-Rich: An excellent source of iron, making it particularly beneficial for women.
Cholesterol Note: The one drawback is its higher cholesterol content.
- Pro-Tip: Pair gizzards with oysters, squid, or clams. These contain taurine, which helps inhibit cholesterol absorption.
