Bladbeans med schalottenlöksmör

👩‍🍳 Gör så här

1. 1
   Top, tail and remove the strings from the runner beans, then cut them diagonally into elongated diamond shapes.
2. 2
   Melt the butter with the oil in a medium-sized frying pan over a low to medium heat. Tip in the shallots and fry them gently for about 8 minutes, or until soft and very slightly coloured. Stir occasionally.
3. 3
   Meanwhile, bring a saucepan of salted water to the boil and cook the beans for 3- 4 minutes until just tender. Drain well.
4. 4
   Turn up the heat under the frying pan and add the sugar and vinegar to the shallots. Stir well and then leave to bubble for 1 minute. Toss the beans and the buttery shallots together, either in the frying pan or saucepan, depending on size. Serve in a warmed dish.
