Pack the mint leaves off their stems—the stems can turn the chutney bitter. Add the water a splash at a time so it stays thick enough to cling. Use lime instead of lemon for a zestier version, or stir in a pinch of cumin or grated ginger for warmth. For a dairy-free chutney, coconut yogurt works well. The flavor deepens as it sits; store in the fridge for up to 3 days. Beyond a dip, try it as a marinade, a sauce for grilled meats, or a spread for flatbread and sandwiches.
