Savoury Rhubarb and Cinnamon Red Lentil Curry

Serves: 4
Takes: 35 mins

Although Rhubarb is a vegetable, the majority of it's uses in cooking are reserved to deserts. It's tangy and crisp flavour pair well with sugar, lending itself well to being used in pies and crumbles. However, rhubarb can be excellent in savoury dishes as well as I attempt to show in this wonderfully simple and light curry.

When To Eat

We recommend eating this dish from February through to June. Forced rhubarb (grown in the dark) appears at the beginning of the year and is tender and tart. In April field grown varieties start to appear which are less tender but more flavoursome.

Heat the oil in a deep frying pan and pour in the onion mixture. Cook for 5 minutes or until the onions are golden and soft.
