Rhubarb season

It must be one of my favorite seasons; the rhubarb season. It’s short but maybe that’s what makes it so special. Whenever the season arrives I look out for those pretty pink stalks in the stores or at the markets. This particular rhubarb cake is super delicious. I love adding almond flour in baking goods as it gives it a better texture and I just love that flavor.

Easy rhubarb cake

Making this rhubarb cake with almond flour is super simple. The only thing you need to keep in mind is that it doesn’t go too fast in the oven. So always check. My friend made it and in her oven it needed more than an hour. In my oven it only took 55 minutes and it was almost too far gone. I would suggest turning the temperature down a bit. in fact that is what I have noted in the recipe below. But keep an eye on it.

Another thing to note is that it makes sense not too use a baking tin that is too big. Mine was 20 centimeter (8 inches) in diameter. If yours is too large, the result will be too flat.

Rhubarb perfection

The cake was perfect the way it turned out. I just randomly placed the rhubarb pieces on top. You can create a pretty pattern if you want, but that’s usually not my cup of tea. Flavor wise it doesn’t make any difference whatsoever.

For making the rhubarb cake it is best to have those pretty pink stalks. Mine where more green or really dark as you can see in the photos. There are many variaties of rhubarb which will determine the color. I kept the pink ones for the top and used the greener ones for inside the cake.

What is the rhubarb season?

You can get rhubarb usually beginning of april. Sometimes a little earlier. The season end mid june.

What is oxalic acid?

Rhubarb contains oxalic acid which – when consumed in large quantities – can give you issues with mineral absorption. It binds itself to the minerals in your body. Rhubarb contains a fair amount of this acid. However you do have to eat quite a lot for it to present real problems.

When does the rhubarb have oxalic acid.

Rhubarb you buy after mid june is usually much more sour. That is when the amount of oxalic acid is higer. So it’s best to use rhubarb that is harvested before mid june. Overal it is really healthy but best not to eat kilo’s of rhubarb at any one time. The advice is to not eat it more than twice a week.

Why are there so many different rhubarb colors?

There are many variaties of rhubarb. This explains why there are so many different colors. The green rhubarb is more sour and firmer and is good for freezing. The pink rhubarb is sweeter and more tastier to eat.

Do I have to precook the rhubarb in the rhubarbcake?

No, that is not necessary. The rhubarb can be processed raw. During the baking process the rhubarb cooks.

Can I replace the almond flour?

If you want you can replace the almond flour with – for instance – chufa flour (tiger nut flour) That can be substituted one on one. However the flavor will be very different. Chufa has a nutty kind of flavor but it very different from almond flour.

I have not tested this with chufa but in other recipes I tend to be able to replace it simply by swapping the quantities almond flour for chufa flour.
