Some recipes—especially those that call for melting chocolate, which burns easily—recommend using a double boiler. If you don’t own one, it’s simple to improvise with kitchenware you already have. Set a heatproof bowl inside a pot of simmering water so the bowl bottom is suspended above the water. The gentle steam provides indirect heat that melts or warms delicate ingredients without scorching, seizing, or clumping.
Homemade double boilers are ideal for sauces like Hollandaise, meringues, custards, and any chocolate-based desserts. Once you know how to set one up, you can use it for many sweets and confections.

What Is a Double Boiler?
A traditional double boiler is two nested vessels: a lower pot holding a few inches of water and an upper pan or bowl that sits above it. When the water simmers, the steam provides gentle, indirect heat to warm or melt ingredients in the top vessel without direct contact with the flame or hot surface, reducing the risk of burning.
How to Make a Homemade Double Boiler
- Choose a pot wide enough to support a metal or glass bowl so the bowl bottom is suspended a few inches above the base of the pot. The bowl should extend above the pot rim so it can be placed and removed easily.
- Pour an inch or two of water into the pot—enough to generate steam but not so high that it will touch the bowl bottom.
- Set the bowl with your ingredients (chopped chocolate, egg yolks, etc.) on top of the saucepan, ensuring the bowl bottom does not contact the water.
- Bring the water to a gentle simmer, stirring the contents of the bowl until melted or the desired consistency is reached. Carefully lift the bowl away from the steam to avoid burns and remove the pot from the heat when finished.
Tips for Making a DIY Double Boiler
- Always use a heatproof bowl—metal or tempered glass works well.
- Make sure the bowl does not touch the water; the goal is steam heat, not boiling water contact.
- Keep the water at a gentle simmer rather than a full boil to maintain even, moderate heat.
- When removing the bowl, lift it away from the pot and watch for hot steam that can cause burns.
- Choose a bowl large enough to sit securely and extend above the pot rim for easier handling.

How to Make a Double Boiler
Equipment
-
1 pot
-
1 heatproof bowl (metal or glass)
Ingredients
- Water (as needed)
- Ingredient to be melted (chocolate, egg yolks, etc.)
Instructions
-
Select a pot wide enough to hold a metal or glass bowl so the bowl bottom is suspended a few inches above the base. The bowl should extend above the pot rim for easy handling.
-
Add an inch or two of water to the pot, ensuring it won’t touch the bottom of the bowl. Place the bowl with the ingredients on top, making sure it remains dry underneath.
-
Heat the water to a gentle simmer (avoid a rolling boil). Stir the contents of the bowl until melted or smooth. Carefully remove the bowl from the pot, being mindful of hot steam, and turn off the heat.
Notes
- Use a heatproof bowl—stainless steel or tempered glass are good options.
- Do not let the bowl bottom touch the water; steam is the heat source.
- Be careful when lifting the bowl—hot steam can cause burns.
