To set up a double boiler bowl, you'll need a heat-proof bowl that fits snugly over a pot of simmering water. This setup allows for gentle heat distribution, which is perfect for melting chocolate or cooking delicate sauces.
The bowl should be at least 1-2 inches above the water's surface to prevent water from splashing in. Make sure the bowl is securely positioned over the pot to avoid any accidents.
The water level in the pot should be about 1-2 inches deep to ensure even heat distribution. Avoid filling the pot too much, as this can cause the water to boil over.
When using a double boiler bowl, it's essential to monitor the temperature and adjust the heat as needed to prevent overheating or scorching.

Creating a Double Boiler Bowl
A heat-safe glass, ceramic, or metal bowl is the way to go for creating a double boiler bowl. This type of material allows for efficient heat transfer.
You'll want to choose a bowl with thinner walls, as heavy stoneware can hinder heat transfer. Metal mixing bowls work well, as they're durable and have thinner walls.
PYREX, a type of heat-friendly borosilicate glass, is also a great choice. Avoid using plastic, even if it's microwave-safe, as it can melt and ruin your saucepan.
The size of the bowl is also important. It should be large enough to cover the top of your pot, but not so large that it feels unbalanced or slides around easily.
170 Degrees Fahrenheit
To reach 170 degrees Fahrenheit, consider using a larger Pyrex bowl and a pot with a corresponding inside diameter. A 2.5 quart Pyrex bowl is 10 inches across at the top.
Using a pot with a 7 inch inside diameter was sufficient to heat the contents of the top of the double boiler to 155 degrees Fahrenheit, so a larger pot would likely be needed to reach 170 degrees.

Boiler Structure and Safety

The double boiler bowl is a simple setup, but it requires some careful consideration to get it right.
The big bowl on top should fit snugly over the sauce pot, not sinking all the way into the pot and not resting on the rim either. It should sit tightly, about 2-3 inches into the pot.
The water level is critical - the boiling water should never actually touch the bowl.
You should be able to see the water boiling through the bottom of the bowl and the moisture collecting on the underside, but you should make sure it doesn’t actually touch.
To ensure the bowl doesn’t touch the boiling water, bring the water up to a full boil before fitting the bowl on top. This will allow you to see if the bottom of the bowl is going to touch the boiling water.
