    Sweet potato mash with soy sauce and salad onions

    • Preparation time: 10 minutes
    • Cooking time: 25 minutes
    • Total time: 35 minutes

    Serves: 4 as a side


    4 large sweet potatoes, peeled
    1 tbsp sesame seeds
    40g unsalted butter
    2½ tbsp soy sauce
    3 salad onions, finely sliced


    1. Roughly chop the sweet potatoes and put in a pan of salted water. Bring to the boil, then reduce the heat and simmer for 20-25 minutes, until tender. Meanwhile, toast the sesame seeds in a dry pan until fragrant (1-2 minutes).
