The best ratio of chia seeds to milk (or non-dairy) in a chocolate and matcha chia seed pudding will vary depending on your personal preference and the desired consistency of the pudding. However, we have found a ratio of 1:4 is not too firm nor too soft. 1 cup of non-dairy or dairy milk to 4 tablespoons (1/4 cup) whole chia seeds is a common chia pudding ratio. This ratio should create a thick, pudding-like consistency, but you can adjust the ratio to make the pudding thicker or thinner to your liking. For example, if you prefer a thicker pudding, you can use a 1:3 ratio of chia seeds to milk. If you prefer a thinner pudding, you can use a 1:5 ratio.
