Individual Rhubarb Crumble Revisited

Mini rhubarb crumble is revisited with a chilled French twist and low in sugar. Served individually with a white chocolate mousse with rose, it's topped with toasted oats.

Ideal for entertaining, this is a simple make-ahead dessert - both the rhubarb and strawberry compote and crunchy oat crumble freeze well too.

Last night I gave it a go, (...) and I even did the magic with the red tea which added a wonderful flavour too. The compote, the white chocolate mousse as well as the oat topping – this dessert is a perfect composition of sweet and sour, thank you, Jill!

Why We Love Individual Rhubarb Crumble

If you love entertaining and being organised ahead of time, then these mini rhubarb crumble desserts are perfect. Each of the three layers are made in advance: the fruit compote, white chocolate mousse and oat crumble.

Even the compote and crumble can be frozen, so this dessert can be made at any time of year.

As a result, it's an easy dessert to prepare up to a week or a day before for dinner parties or lunches outside on the terrace.

What Can you do with a lot of Rhubarb?

Some of us are lucky to have neighbours who grow rhubarb plus, in Spring, it is becoming so much more popular than ever at our French markets. If you're like our family who adores rhubarb, we buy so much that I'm often flashed puzzled looks from French locals, who ask me each year, "What are you going to do with all that rhubarb?"

My quick answer is rhubarb compote (or stewed rhubarb). I dollop it on granola, rice pudding, on ice cream or just eat it on its own. It's also perfect as a base for this dessert. What's more, it freezes so well that you can have rhubarb compote at any time of year.

However, I appreciate not everyone has easy access to rhubarb. So, I've updated this recipe. Either make it just with rhubarb, with strawberries, or replace the rhubarb with strawberries instead. They all work well.

What Other Fruit Goes With Rhubarb?

When I first published this recipe, I made it purely with rhubarb but now I've dared to add strawberries, as this is another fruit that goes so well with it.

Don't have rhubarb? I've tried the same recipe completely with strawberries - and it's just as delicious.
If you do make this recipe using just strawberries, add less sugar, as strawberries are naturally sweeter than rhubarb. My ratio of rhubarb to sugar is 4:1, the ratio for strawberry compote is 5:1.

Do you Need to Peel Rhubarb for a Crumble?

First prepare the rhubarb for the crumbles. You may need to peel the rhubarb if the skin is particularly thick and stringy but otherwise I leave it on and cut into slices, discarding the leaves. All is shown in this video demonstration for preparing rhubarb.

Do you need to pre-cook the Rhubarb for Crumble?

The short answer is yes - for this recipe. Rhubarb is extremely sour if eaten raw. On the other hand, my Scottish grandpa used to eat a stick of rhubarb raw and dip it in sugar. Just thinking of it makes me salivate!

Although it was good, it's an acquired taste. It was too sour for me so this low sugar rhubarb compote is my answer to please everyone in the family. Compote is a healthy version of jam, as it only uses half the amount of sugar and so it's a delicious healthy base for making these chilled rhubarb crumbles.

Rhubarb Crumble with Oats and Mousse

Normally in Britain, we'd serve a rhubarb crumble warm from the oven with hot, thick custard. This, however, is my French twist to the classic comfort dessert. Instead, serve the mini rhubarb crumble well chilled individually in glass dishes with this light and fluffy white chocolate mousse.

How did I develop this recipe? I took inspiration from Michelin-starred French chef, Anne-Sophie Pic's beautiful book for entertaining, Recettes pour Reçevoir with her restructured style recipe for Rhubarb tart with tarragon. Served in glass verrine dishes, she layers rhubarb compote with shortbread and tops with a white chocolate espuma using a siphon.

Instead, I made this oat crumble version, as I love the crunchy texture in this dessert. I omitted the mousse's sugar completely (I find white chocolate is sweet enough) and added a touch of rose (and/or orange blossom water) - inspired by my white chocolate mousse, made without a siphon.

Can I make this Mousse without a Siphon?

Don't worry if you don't have a siphon: just follow my easy recipe for White Chocolate, Rose and Orange Blossom Mousse.

Crunchy Rhubarb Oat Crumble - the Topping

As I love a good crunchy Scottish apple crumble with oats, this topping is toasted in the oven and just crumbled directly into the glass.

Serve in mini shot glasses or verrines. If you like a toasted oat crumble topping like this, you should try this French Apple Crumble Cake.

Ideas How to Serve

This dessert can easily be made in advance and assembled at the last minute. The following garnishes can also be prepared in advance, giving the individual rhubarb crumbles an extra wow factor. Here are some ideas - or add your own creativity and share them in the comments below.

• Top with macarons or macaron shells (they're also handy to keep in the freezer);
• Serve with almond tuiles;
• Top with a strawberry or rose petal (brush with egg white, coat in sugar and dry for an hour);
• Serve with dried rhubarb chips (crisps).

This recipe was first published in June 2017 but has now been completely updated with new images, a video and the recipe now includes strawberries.
