Tips on how to make rhubarb crumble with oats even better

The oatmeal in this rhubarb crumble recipe is perfect for giving that crunch and sweet feeling that complements the sourish rhubarbs so perfectly. But there is no rule as to what rhubarb crumble ingredients you must use. Experiment a bit with the recipe to find the perfect combination of flavours to your liking.

You can add almonds to the oatmeal crumble to give an extra crunchy feeling. Ginger and vanilla are also perfect additions to your rhubarb crumble recipe depending on how sweet or savoury you like it.

Balance the sourish rhubarb with sugar and sweet vanilla if you like a sugary dessert and leave out a bit of sugar if you want it sourer. But be sure to not make it too sour – because of the low levels of oxalic acid in the rhubarbs, you will feel it on your teeth and have a hard time enjoying it if you leave out too much sweetness.

If you want to make the rhubarb crumble recipe a bit easier, you can use Lurpak® mini blocks. Then the butter is ready to use without you having to do anything else than unwrapping it and putting it in the batter. To balance out the sweet and sour, you can use Lurpak® slightly salted butter, which is also the type used in the mini blocks.

Use the right topping

The rhubarb crumble with oats is not always enough on itself. You need to use the right topping as the "cherry on top" of your already delicious crumble. You can either use a sour crème fraiche to balance the sweet crumble, especially if you add vanilla to the rhubarbs, or a cool whipped cream. If you go for the sweeter option with whipped cream, you can add a splash of vanilla to make it even sweeter.

Drizzle almond flakes on top of the crème fraiche or whipped cream or chop up some hard caramel or pecan nuts to make it more crunchy.

Can you freeze rhubarb crumble?
