Chocolate PB

A home guide to chocolate

Know your chocolate, then melt it, bake with it and keep it well

Plain guides for home cooks: what the number on the wrapper means, how to temper without special gear, why chocolate turns gray, and a handful of easy recipes. Peanut butter turns up often.

Where to start

Most chocolate trouble at home comes from three things: picking a bar that does not suit the recipe, heating it too fast, and storing it somewhere too warm or damp. The guides below take those in order.

What is in the bar

Each bar below has 20 squares. A dark square is cacao, a pale gold square is cocoa butter on its own, a tan square is milk solids, and a speckled square is sugar. Reading the bars left to right shows how the sweetness and the cocoa flavor trade places as the percentage drops.

Unsweetened

100% cacao

Ground cacao with nothing added. Very bitter. Made for recipes that bring their own sugar.

  • Cacao100%

Bittersweet

About 70% cacao

Deep and only lightly sweet. A good all-round dark chocolate for ganache, sauces and baking.

  • Cacao70%
  • Sugar30%

Semisweet

About 55% cacao

The familiar baking chip flavor. Sweeter and milder than bittersweet.

  • Cacao55%
  • Sugar45%

Milk

About 35% cacao

Creamy and sweet, with milk powder in the mix. Softer when melted and easier to scorch.

  • Cacao35%
  • Milk solids20%
  • Sugar45%

White

About 30% cocoa butter

Cocoa butter, milk and sugar, with no cocoa solids. The most heat-sensitive of the five.

  • Cocoa butter30%
  • Milk solids25%
  • Sugar45%

Each bar has 20 squares, and each square stands for about 5% of the weight. The splits are rounded examples. Real bars vary by maker, and small amounts of vanilla or an emulsifier are left out.

The cacao percentage guide explains the numbers in more detail and has a slider that builds a bar for any percentage.

Tempering at a glance

Tempered chocolate snaps cleanly, shines and does not melt the moment you touch it. To get there with the seed method, melt the chocolate fully, then cool it to its working temperature by stirring in chopped chocolate that was already tempered. These rounded figures are a common starting point. If the maker prints its own temperatures on the package, follow those.

ChocolateMelt to (°F)Melt to (°C)Work at (°F)Work at (°C)
Dark115 to 12046 to 4988 to 9031 to 32
Milk110 to 11543 to 4686 to 8830 to 31
White105 to 11040 to 4382 to 8428 to 29

The full method, with tests and fixes, is on the tempering page. If you only need melted chocolate for a batter or a drizzle that will be chilled, the melting guide is enough.

A word on allergens

Many chocolates contain milk, and many contain soy lecithin. Peanuts and tree nuts are often handled in the same factories, so read the "contains" and "may contain" lines on every package. Several recipes here use peanuts or peanut butter. The allergen page lists what to look for and suggests swaps.

Common questions

Is a higher cacao percentage always better?

No. A higher number means less sugar and a stronger, more bitter cocoa flavor. That suits some recipes and some people. A brownie recipe written for semisweet chocolate can turn dry and bitter with a 90% bar.

Do I need to temper chocolate for baking?

No. Chocolate that goes into a batter, a ganache or a sauce does not need tempering. Tempering matters when the chocolate is the outside of something, such as a dipped strawberry or a molded bar, and you want it to set firm and glossy at room temperature.

Why is the site called Chocolate PB?

Chocolate and peanut butter is one of the most popular pairings in American kitchens, so it runs through the recipes. The guides themselves cover chocolate in general. See the about page for what we cover and what we leave out.
