High School Track·Homemade butter from cream
Homemade butter from cream
Mechanical agitation of cream causes fat globules to collide and coalesce, separating butterfat (butter) from buttermilk, a real, simple dairy-science process.
Where to buy & price
Just examples of where to look and roughly what to expect to pay, get everything from wherever works for you, at whatever price you find.
Fresh cream, Naivas/Quickmart dairy section, ~KSh 150–250/250ml.
Cold storage / timing
The cream should be slightly chilled (fridge, ~30 minutes before starting), this is a real requirement, as cream that's too warm won't separate properly; the finished butter should then be refrigerated to firm up.
Reagents & materials required
| Fresh heavy/whipping cream | 1-2 cups, enough to half-fill your jar |
Procedure, step by step
- 1
Chill fresh heavy or whipping cream in the fridge for about 30 minutes before starting.
- 2
Pour the cold cream into a clean jar with a tight-fitting lid, filling it no more than halfway to leave room for movement.
- 3
Seal the jar tightly and shake vigorously and continuously, this typically takes 10–20 minutes by hand, or just a few minutes with an electric mixer.
- 4
Watch the texture change in order: first it thickens into whipped cream, then it turns grainy and starts to separate.
- 5
Keep shaking until you see solid yellow clumps of butter clearly separating from a thin, milky liquid, the buttermilk.
- 6
Pour off and keep the buttermilk (it's genuinely useful for baking), then press the solid butter clump gently to squeeze out any remaining liquid.
- 7
Rinse the butter briefly under cold water while pressing it, to remove residual buttermilk and help it keep longer.
- 8
Refrigerate the finished butter to firm it up before use.
