You need first some shells like that made with caramel doré.

We first fill them with caramel fill

And then I will sprinkle them with salted caramel crispers.

Okay, the first half must be finished right now with another caramel filling and you pipe it a little bit over the top.

When it's filled, you just need to scrape it.

Now we continue with the other half and we will fill it with a hazelnut praline.

And now we'll wait until it crystallizes.

And now you see, they're ready.

We just take them out of the mold and place them on the tray.

Now we'll stick the other part on the top, just a drop and here the other part, we stick it on the top.

And now we continue with the very last step, which is the hand rubbing process.

So you need these kind of tray and carefully you place the volcanoes on the T's.

For the last finishing, you need two piping bags, one with caramel doré, one with dark chocolate.

You first pipe the caramel doré like that, start with two

and then you do the stripes in dark chocolate.

And now when it is finished, you have a beautiful symphony of caramel volcano.
