Step by step to prepare the soup

With all the utensils and ingredients ready, we will proceed with preparing the kumquat soup with rhubarb and tomato.

Step 1: Cut the main ingredients

Take the rhubarbs and kumquats, wash them with plenty of water, and cut them. Cut the rhubarbs into small pieces and the kumquats into thin slices.

Step 2: Empty the kumquats

Remove all the bones (the seeds) you will not need.

Step 3: Cut the other ingredients

Now wash and cut into small pieces the cherry tomatoes (should be peeled), the basil sprouts, and fresh citronella.

Step 4: Prepare a syrup

Put water in a pot and let it heat. After that, add sugar and dissolve it, stirring with a wooden pallet until you get a thick substance.

Step 5: Integrate the ingredients into the syrup

Already having the syrup ready, we will add the pieces of cherry tomato, basil, citronella, and some kumquat slices, mix well, and let it rest for 20 minutes until it cools completely.

Step 6: Reserve the syrup

After the syrup is at the right temperature, we will temporarily change the container and reserve it in the fridge.

Step 7: Texturing kumquat

While we liquefy the kumquat or crush it with an electric mixer, we will add the xanthan (a thickener from corn starch). Liquefy until we see a homogeneous mixture. If you do not have xanthan, you can choose to replace it with corn starch.

Step 8: Store the mixture in the fridge

As soon as the mixture is complete, we will place it in a pastry bag, and we will store it in the fridge for about 20 minutes to let the mixture rest and compact more.

Step 9: Blend the rhubarb

Add the rhubarb, celery, apple, and a few basil leaves (medium pieces). Blend until you see that everything looks like pulp. You can help yourself by adding a little water so you won’t force the blender much.

Step 10: Cooking the soup

Then, pour the liquefied rhubarb mixture into a medium pot and place it on the stove at medium heat. Please wait for it to boil a little and remove it.

Step 11: We serve and taste

Serve the broth in a deep dish, and on top of the broth, place the syrup well-drained. To accompany this exquisite dish, cut bread into slices and toast it. Then, with the mixture of kumquat in the pastry sleeve, we make a spiral shape on each piece of bread and ready an exquisite and exotic dish served to your table.
