    What is the Musui–Kamado?

    The Musui–Kamado is our innovative cast iron induction cooker. It is made up of the Musui, our handcrafted enameled cast iron pot with signature precision seal, and the Kamado, our state-of-the-art induction heating base that delivers three-dimensional heating and precision heat control.

    Together, the Musui–Kamado helps home chefs create more consistent and restaurant-quality meals right at home.

    What is included when I purchase the Musui–Kamado?

    Your purchase will come with the 3.9 qt Musui enameled cast iron pot and the Kamado induction heating base. It will also include the following accessories: a Vermicular cookbook with over 70 original recipes, 2 measuring cups (one each for water and rice) and a cast iron lid stand.

    What is the "precision seal" and why is it important?

    Our signature precision seal is designed to condense the natural flavors of ingredients. We meticulously machine the contact area of the pot and lid of the Musui to less than .01 mm of variance, creating a precision seal that maximizes moisture retention and emphasizes the complex flavor profiles of each individual ingredient.

    Instead of using water, excess seasoning or sauces, let the ingredients do the work.

    What is “three-dimensional heating"?

    Inspired by traditional Japanese kamado stoves, the Musui–Kamado creates three-dimensional heating by combining:

    1. High-performance induction coils at the base of the Kamado and

    2. An aluminum surround heater that hugs the sides of the Musui enameled cast iron pot

    The result is perfect heat distribution, far exceeding the performance of induction cooktops or gas stoves. No more "hot/cold" spots while cooking.

    How does “precision temperature control” work?

    The Musui–Kamado makes precision cooking simple. It allows you to sous-vide without the hassle of vacuum-sealing or make temperature-sensitive recipes like poached eggs and custards. You can also proof dough, make yogurt or even craft your own miso.

    Additionally, the Kamado's built-in heat sensor monitors and optimizes heat levels for streamlined heat control:

    • Medium [MED] heat: 445ºF
    • Low [LOW] heat: 300ºF
    • Extremely Low [EXT LOW] heat: 230ºF
    • Warm [WARM]: Adjustable, from 90-200ºF

    Are there recipes available?

    Yes, every purchase of a Musui–Kamado or standalone Musui comes with a Vermicular cookbook with over 70 original recipes to get you started. Preview a few of our original recipes here.

    Can I use the product in the oven or stovetop?

    The Musui can be used both with the Kamado and on its own without the Kamado.

    Using the Musui without the Kamado: On its own, the Musui can be used with any gas or electric stovetop, induction cooktop and oven (oven safe up to 570ºF). Please do not use with microwaves.

    Product Care
    How should I clean my Musui–Kamado?

    For the Musui: Do not use any abrasive cleaners to clean. Dry the pot immediately after washing. The contact area of the pot and lid is not enamel-coated and can potentially rust, so make sure the rims are dried thoroughly with a dry cloth.

    For the Kamado: Wipe clean with a damp cloth once powered off and cooled down. For tough stains, use a soft cloth with mild dish soap to clean and dry thoroughly with a separate dry cloth. Do not wash the Kamado directly with water, as it is an induction cooker with electrical parts. Immersing in water may result in fire or electric shock.

    What if my Musui has rust?

    To achieve our signature precision seal, the contact area of the pot and lid is not enamel-coated and can potentially rust. To minimize rust, make sure the rims are dried thoroughly immediately after washing. If you see rust, clean off with mild dish soap. If you still cannot get rid of the rust, use a rust remover.

    What about stains or if food gets burnt and stuck onto my Musui?

    To remove stubborn burnt food: Fill the pot with enough water to cover the burnt food, add 2–3 tablespoons of baking soda and boil water over medium heat for about 10 minutes. Once cooled, gently scrub with a soft sponge. Repeat this step several times until clean. Never scrub with force or with abrasive cleaners.

    To remove stains: If the enamel gets stained, use only non-abrasive cleaners or cookware-safe bleach with a soft brush or sponge.
