How to make the best rhubarb crumble
Are there things tastier than a good rhubarb crumble? Then again, I don’t think so. In any case, this one is delicious to make!
This rhubarb crumble has a bit of a history. The very first time I made it – already years ago – I had seen it pass by on the blog of Ellen from MadebyEllen. It looked amazingly delicious and seemed like the perfect recipe for the visitors who were coming over later that day.
So I happily got to work and everything looked great. I used a regular oven dish to make the rhubarb crumble. It seemed convenient and it was about the right size. Until the moment I wanted to take the rhubarb crumble out of the dish and then there was no way I could get through that bottom.
The photo you see below is still from that time. You can see from the look of the rhubarb crumble in the baking dish that it didn’t go quite right. But the taste was delicious so it seemed to me that I should do that again. But then properly.
In the remake
So the rhubarb crumble went into the remake and thankfully a lot better this time. I still don’t know what went wrong that first time. I suspect something with that oven dish, but anyway; this time I baked the rhubarb crumble in a regular 20 x 30 cm baking pan lined with baking paper and it went perfectly. Phieuw. You can also use a square pan to bake it.
To make the rhubarb filling for the rhubarb crumble, start by making the rhubarb compote. That’s basically done in no time. I used about 1000 g rhubarb. After cleaning it, there was about 850 grams left. I put the rhubarb pieces in a pan with the orange juice and granulated sugar and a teaspoon of vanilla extract.
There is not too much sugar going into the rhubarb mixture. This also because there is already sugar going into the bottom and into the crumble so the end result is a lovely fresh rhubarb crumble. You do still want to taste that delicious sourness of rhubarb. For added flavor I add a bit of orange juice into the rhubarb. You can also add orange zest or lemon juice to it, if you want.
The first time I made it, I was a little concerned about the fact that you pour the rhubarb compote on the bottom like that. As you can imagine, there is quite a bit of rhubarb juice from the compote, so I was a little worried that it wouldn’t turn out well. But no need to worry about that.
Right after baking it is still a bit soft, but after a night in the fridge the rhubarb crumble is firm enough. You can make it earlier, but it will be softer in texture.
Making the bottom of the rhubarb crumble
To make the crust, you need a large bowl and a food processor can come in handy too. You either mix the ingredients by hand in the mixing bowl or you can use the food processor to make sure you get the dough just right. I used all purpose flour and regular granulated white sugar. You can also use golden caster sugar if you prefer. That will give it a slightly different flavor. But is definitely also a good option to use. Also add in about half a teaspoon salt.
Once the dough mixture is made you press it into the pie dish. Do make sure you line the baking tin with baking paper. That makes a whole lot of difference. I press the dough into the container with my hands. That is the easiest way. I then use a fork to prick a few holes in the bottom. And bake it in the oven at 180˚C (350˚F) It needs about 15 minutes to become very light golden brown. You take it out of the oven and now is the time to pour in the stewed rhubarb.
On top of the rhubarb crumble is a very easy crumble topping. To make the crumble mixture I use equal amounts of about a quarter of a cup of flour, quarter cup oats, quarter cup sugar and the same amount of butter. You add the pieces of butter last and use your fingers to rub it into a crumble.
Sprinkle the crumbs (and it’s ok if they’re coarse crumbs) over the top of the rhubarb compote and place in the oven.
You leave the rhubarb crumble in the oven for another 20 minutes or so or until the top is nice and golden brown. Remove from the oven and let cool thoroughly in the tin. It will be firmest if you refrigerate it overnight but if you can’t control yourself then there is certainly nothing wrong with cutting it before then. The rhubarb crumble is best served at room temperature.
How long can you keep the rhubarb crumble?
You can safely keep the rhubarb crumble in the refrigerator for about five days. Do cover it to prevent it from picking up other odors from the refrigerator. Or use an airtight container to store it in the fridge.
