Important Safety Instructions

Please read all instructions carefully before using your Iwachu Gohan Nabe. Failure to follow these instructions may result in injury or damage to the product.

• Heat: Cast iron gets extremely hot. Always use oven mitts or heat-resistant gloves when handling the pot and lid during and after cooking.
• Surfaces: Place the hot pot only on heat-resistant surfaces or trivets.
• Children: Keep out of reach of children.
• Lid: Be cautious when removing the lid, as hot steam will escape. Always lift the lid away from your face.
• Cracks/Damage: Do not use if the pot or lid is cracked or damaged.
• Stovetop Use: This rice cooker is designed for stovetop use. Ensure it is placed on a stable, level surface on your cooktop.

Setup and First Use

Before using your Iwachu Gohan Nabe for the first time, follow these steps:

1. Wash: Wash the pot and lid thoroughly with warm water and a mild dish soap. Use a soft sponge or cloth.
2. Rinse: Rinse completely to remove all soap residue.
3. Dry: Dry the pot and lid immediately and completely with a clean towel. Cast iron is prone to rust if left wet.
4. Season (Initial): While the pot is pre-seasoned, an initial seasoning can enhance its non-stick properties and protect it. Apply a very thin, even layer of high smoke point cooking oil (e.g., vegetable oil, grapeseed oil) to the entire interior surface of the pot and the underside of the lid. Wipe off any excess oil.
5. Heat (Initial Seasoning): Place the pot and lid (separately) in an oven preheated to 350-400°F (175-200°C) for one hour. Turn off the oven and let them cool completely inside the oven. Alternatively, you can heat the pot on a stovetop over medium-low heat until it begins to smoke lightly, then turn off the heat and let it cool.

Operating Instructions: Cooking Rice

The Iwachu Gohan Nabe excels at cooking various types of rice. Here is a general guide for cooking white rice. Adjustments may be needed based on rice type and personal preference.

Basic White Rice Cooking Method

1. Rinse Rice: Measure your desired amount of rice (e.g., 1-2 cups). Rinse the rice thoroughly under cold running water until the water runs clear. This typically takes 3-4 rinses.
2. Soak Rice (Optional but Recommended): For best results with Japonica varieties, jasmine, or basmati rice, soak the rinsed rice in clean water for 30 minutes. Drain the rice completely for another 30 minutes.
3. Add Water: For most white rice, use a 1:1 ratio of rice to water (e.g., 1 cup rice to 1 cup water). For Jasmine rice, a 1:1.5 ratio (1 part rice to 1.5 parts water) is often preferred. You can add a pinch of salt to the water if desired.
4. Bring to Boil: Place the pot with rice and water on high heat on your stovetop. Bring the water to a rolling boil.
5. Stir and Cover: Once boiling, give the rice a quick stir, scraping the bottom to prevent sticking. Immediately place the heavy lid firmly on the pot.
6. Reduce Heat: Reduce the heat to the lowest possible setting.
7. Simmer: Let the rice simmer undisturbed for 10-15 minutes. Do not lift the lid during this time.
8. Rest: After the simmering time, turn off the heat. Remove the pot from the hot burner. You can place 2 paper towels over the pot opening before replacing the lid to absorb excess moisture. Let the rice rest, covered, for another 10-15 minutes. This allows the rice to steam evenly and become fluffy.
9. Fluff and Serve: Remove the lid and fluff the rice gently with a rice paddle or fork. Serve immediately.

Tips for Optimal Results

• The heavy cast iron lid creates a tight seal, crucial for even cooking.
• The raised bumps on the lid's underside help return condensation to the rice, ensuring moisture retention.
• Experiment with water ratios and cooking times to find what works best for your preferred rice type and stovetop.
• The pot's rim channel is designed to catch minor boil-overs, keeping your stovetop cleaner.

Care and Maintenance

Proper care will ensure the longevity and performance of your cast iron Gohan Nabe.

Cleaning

1. Cool Down: Always allow the pot to cool completely before cleaning.
2. Warm Water: Wash with warm water and a stiff brush or non-abrasive sponge. Avoid harsh detergents, as they can strip the seasoning. For stuck-on food, you can gently scrub with a paste of coarse salt and a little water.
3. Avoid Soap (Optional): Some users prefer to avoid soap entirely to preserve seasoning. If you use soap, ensure it's mild.
4. Rinse and Dry Immediately: Rinse thoroughly and dry the pot and lid immediately and completely with a clean, lint-free cloth or paper towel. Do not air dry, as this will lead to rust.

Seasoning

Regular seasoning maintains the non-stick surface and protects against rust.

1. Apply Oil: After drying, apply a very thin layer of high smoke point cooking oil (e.g., vegetable oil, grapeseed oil, flaxseed oil) to the entire interior surface of the pot and the underside of the lid. Wipe off any excess oil with a paper towel until the surface looks dry, not greasy.
2. Heat: Heat the pot on the stovetop over medium-low heat for 5-10 minutes, or until it begins to smoke lightly. This polymerizes the oil, creating a durable, non-stick layer.
3. Cool: Turn off the heat and let the pot cool completely.
4. Repeat (Optional): For a stronger seasoning, you can repeat this process.

Storage

Store your Gohan Nabe in a dry place. If stacking, place a paper towel or cloth between the pot and lid to allow air circulation and prevent moisture buildup.
