Notes
- The yogurt fermentation step is optional if you want sweet cream butter instead of cultured butter. Skip it and simply use cold fresh cream straight from the refrigerator. The churning method and washing steps remain the same. The flavour will be cleaner and milder, closer to standard commercial sweet cream butter.
- The temperature of the cream going into the mixer is the single most important variable in the recipe. Too warm and the butter forms slowly and the texture is greasy. Too cold and it takes much longer than necessary. Around 55 to 60 degrees Fahrenheit is the ideal, which for most refrigerators means taking the cream out 20 to 30 minutes before churning.
- The real buttermilk that comes off during churning is thinner and more liquid than commercial buttermilk and is better in every baking application. Use it immediately or refrigerate and use within a week.
- The compound butter applications are where this recipe genuinely earns its place over commercial butter. After salting, incorporate roasted garlic and thyme for a steak butter, or honey and flaky sea salt for a breakfast butter, or blue cheese and chives for a burger butter, before shaping and wrapping. These versions genuinely cost less to produce at home than the equivalent commercial product and taste noticeably better.
