Butter
Learn the culinary uses, pH levels, and storage qualities of butter for everyday cooking.
Classification: Emulsified milk fat (min. 80% butterfat)
pH Level: 6.1 - 6.4
A water-in-oil emulsion crafted from cream, providing rich dairy flavor and chemical leavening properties.
Common Culinary Roles
- ⯅Laminated into pastries for delicate, flaky layers.
- ⯅Whisked cold into hot sauces (monter au beurre) for silkiness and gloss.
- ⯅Sautéing medium-heat aromatics to infuse buttery richness.
Storage Guidelines
- ▪Store in the refrigerator below 40°F (4°C) in its moisture-proof wrapper.
- ▪Can be frozen in airtight packaging for up to nine months.
- ▪Keep covered to prevent the fat from absorbing ambient odors from the fridge.
Cooking Behavior & Heat Reactions
Butter is a delicate water-in-fat emulsion. At 90°F to 95°F (32°C - 35°C), the lipid crystal matrix collapses, melting into liquid fats. Past 212°F (100°C), the water content evaporates, causing bubbling. Around 250°F to 300°F (121°C - 149°C), the suspended milk proteins undergo the Maillard reaction, turning brown (beurre noisette) and releasing a nutty fragrance.

Cooking Standards FAQ
Q:Can I use salted butter instead of unsalted butter in baking?
Yes, but you should adjust the recipe's added salt. Salted butter typically contains about 1/4 teaspoon of salt per stick (1/2 cup), which can affect the hydration and rise if not counter-balanced.
Q:Why does butter splutter in a frying pan?
Butter contains about 16-18% water. When heated, this trapped water reaches boiling point and bursts through the surrounding oil layer as steam, causing popping and spluttering.
