First, soak the gelatin in cold water for 10 minutes to soften it.
Combine cream, milk, parmesan, salt and pepper in a saucepan, mix well, bring to a boil, stirring constantly, cook for another minute and turn off.
Remove from the heat, squeeze in the gelatin, and stir immediately to dissolve completely.
With some care, immediately transfer the mixture while hot to the molds, first let it cool at room temperature, then refrigerate at least overnight.
Next, pay attention to the onions. Peel and cut first in half and then into thin slices.
Place in a non-stick saucepan with salt and a little oil and simmer over low heat until wilted. Then add the vinegar and sugar, let the vinegar evaporate and continue to simmer for another 15 minutes or until tender. Cooked.
Cut a disc from the bread the same diameter as the panna cotta mold (or slightly larger) and gently flip the panna cotta over.
Start assembly. Place a bread disk on a cutting board or plate, place the panna cotta on top, and top with a little onion.
Roughly crush the tarari to complete the panna cotta.
Once your delicious panna cotta with onions is ready, all you need to do is bring it to the table and surprise all your guests.
