I want to make a dessert that simulates a salmon roe sushi (like this) using rice pudding and spherified melon juice with a chocolate "seaweed" wrapping. But I can't figure out how to make the seaweed convincing.
How do I do this?
"Plastic chocolate" is a form of chocolate used for modeling and shaping decorative elements such as chocolate roses, ribbons and other elements for cakes and desserts.
Take about 1 lb. of bittersweet chocolate and melt over a double boiler. When chocolate is melted, stir in 2/3 cup of light corn syrup. Mix until evenly blended and then set aside to cool. When it firms up, wrap tightly in a heavy gauge plastic bag or wrap tightly in plastic wrap. Let sit for several hours or overnight. No need to refrigerate it, ambient temperature is fine.
Cut the plastic chocolate into smaller size chunks that will be easy to knead. Begin kneading to soften it. If it gets sticky, use a little cocoa powder but be careful not to dry it out. Knead until pliable and then roll out to desired thickness and cut as desired to shape your sushi rolls, decorative elements, etc. You can roll it through the roller of a pasta machine to help get it to an even thickness.
If you're wanting the rough look of nori then press some crumpled foil into it after rolling as previously suggested.
So I made this. It worked out really well. The recipe leaves some room for improvement, but overall, I was happy with the way it turned out.
I rolled out the chocolate, pressed crumpled tin foil in, and then made the nori.
The dish put together.
Dessert for four.
I used reverse spherification of peach puree for the caviar, sliced peaches as ginger, raspberry sauce as soy, rice pudding as sushi rice, and pistachio butter as wasabi. The presentation was great. The flavor was good.
Some things that could greatly help this dish:
I welcome thoughts or suggestions in the comments.
I don't do much with chocolate, so I don't know if you can mold in it, but I think a mold made of crumpled and flattened tin foil would give a pretty convincing texture.
How about using a fondant instead of chocolate? Roll it thin enough then wrap with a sushi mat to get the bamboo texture onto it.
