Heat coconut oil and add 100 g coconut oil to the Thermomix bowl. Heat 2 min / 60°C / speed 2 until melted and clear. Scrape down.
Add soymilk, tapioca, nutritional yeast, miso, vermouth, kappa, salt, mustard, and coriander.
Blend 20 sec / speed 6, scrape down, then 10 sec / speed 8 until smooth and uniform.
Cook 8 min / 90°C / speed 3 with the measuring cup off. The mixture will become glossy, elastic, and thick. If still loose after 8 min, cook an additional 1-2 min.
Pour immediately into the prepared 2-cup (500 ml) mold. Tap gently to remove bubbles.
Cool at room temperature for 30 min, then refrigerate at least 6 hours or overnight until firm.
