How to Use Four simple steps to enjoy yogurt easily: 1) Pour yogurt into the strainer. 2) Refrigerate for 48 hours. 3) Remove and serve. 4) Strain the whey to serve. Note: Filtration occurs during refrigeration; longer filtration time results in thicker yogurt. If you want a thicker texture, refrigerate for more than 48 hours.

When the strainer is removed, it can be used as a fruit carrying box. Large capacity of 1100 ml allows you to hold a substantial amount of yogurt.

The Fine Mesh Bag is removable for easy cleaning; rinse or brush to remove residue.
