First cut the celeriac in half and clean it. Then cut it in even small cubes. In total you need 150 grams of cubes.
Now transfer them into a pan and also add the celery base. Bring this to a boil and reduce it till the total weight is 200 grams.
Then transfer it into a measuring cub or a blender. Add the isomalt sugar, the lime juice, the egg white, the glucose and the salt. Now blend this till smooth.
Because it has been heated for so long the color has faded, to fix this I added a couple leaves of parsley, but spinach is also fine. Blend it till smooth to restore the color.
Then spread it on a silicon sheet using a stencil. Click here for more info. Now remove the stencil and dry them at 95 °C for 2.5 hours. Once they are completely dry transfer them one by one on bottom of the tartelette mold and heat them up at the same temperature for a minute or three. Then use the top to press down the disc and shape the tartelettes.
After that let them cool down completely and keep them dry and covered for later.
Now a little trick, these tartelettes can turn soft quite fast once filled. Especially with a moist filling. To delay this process I cut some spinach leaves with the cutter from the mold and added a drizzle of oil. Now make sure everything is covered and place them between the tartelette mold. Let this dry at 95 °C as well for around 1 to 2 hours. This will be the bottom layer when plating the tartelette and it makes a real difference for the texture.
