Ever since I spent a period at the Lanesborough’s sister hotel, the Mansion on Turtle Creek in Dallas, I have been partial to a Margarita or two, so much so that I now use tequila occasionally in cooking. It works perfectly with kumera (orange sweet potatoes) and passion-fruit.
Pour over the maple syrup, tequila and passionfruit juice, toss lightly and return to the oven until the potatoes have caramelised. Sprinkle over the marjoram and toss once more. Place in a serving dish and scatter over the almonds, if using.
