One cup of fresh raspberries smashes directly into the oat mixture — seeds, juice, and all — creating pink swirls that deepen in color as the jars chill overnight. Two tablespoons of flaxseed meal thicken the plant-based milk into something closer to pudding by morning. Maple syrup is optional; the raspberries provide enough sweetness on their own. Scatter a quarter-cup of chopped pistachios over each jar just before eating so they stay crunchy. Serves 2; total time is about 6 hours including the overnight chill.
