Grilled apricots with custard Photo by Babiche Martens. Add a pinch of turmeric and no more, or your custard will become bright yellow. I used oat milk, but almond or soy are also great. The less-watery milks make for a creamier texture. A sneaky extra dash of maple is allowed if you have a sweet tooth. Ingredients Directions To make the custard, combine the cornflour and water with a pinch of turmeric. Heat the milk in a medium sized pot until just boiling. Stir through the cornflour mixture until the custard is smooth and has thickened. Add the maple and vanilla to taste.
