popular, sweet-tart Haitian marmalade or jam made from grapefruit (chadèk), often featuring a balance of sweet and tangy flavors with hints of spices like cinnamon, star anise, and vanilla, resulting in a rich, spreadable preserve perfect for toast, pastries, cheese boards, or as a glaze for meats. The distinct flavor comes from preparing the grapefruit pith by rinsing and boiling it multiple times to reduce its natural bitterness before slow-cooking with sugar and other ingredients.
