Creamy Blueberry Lemon Overnight Oats with Yoghurt and Chia

Use one 500ml covered pot per serving and a 2l covered mixing bowl for each batch of up to two servings. For larger households, divide all ingredients between batches first; in each step use that batch’s share of the displayed total amount. Rinse the blueberries and reserve 30g. Wash the lemon and measure 2g finely grated yellow zest, avoiding the white pith. Save the unused lemon for another meal.
