Basic Milk Kefir Recipe

• Ingredients: 1 tbsp active milk kefir grains, 2 cups dairy milk (whole milk preferred).
• Equipment: Glass jar, choose either a breathable cover (coffee filter, cloth) or use a sealed jar, plastic strainer.

Directions:

• Add grains to the jar, pour in milk, and cover.
• Ferment at room temperature () for 18–30 hours, or until thickened.
• Strain the grains (plastic sieve recommended), reserving the kefir grains.
• Place grains in a new jar with fresh milk for a new batch.

Look for grains on Facebook Marketplace or ask anyone locally who makes milk kefir as they will have excess (the grains multiply).
