I came up with this recipe to cloak the following football shaped flourless chocolate cake filled with bittersweet chocolate ganache.
1 cup walnuts
1 cup powder sugar, sifted
1 tablespoon light corn syrup
1 tablespoon walnut oil
water and additional powder sugar (optional, to make dough pliable if too dry or crumbly)
Preheat oven to 350F and roast walnuts for 5-10 minutes to release their oil/flavors.
Cool walnuts and then process in food processor (for 5 minutes) until pasty.
Add powder sugar, corn syrup and walnut oil and process until smooth.
Turn onto table and knead until smooth and pliable. Use water and/or additional power sugar to achieve this if necessary. You should end up w/ a dough that can be shaped and/or rolled.
