Substituting for Triple Sec (for Passover)

[rockycat]

I'm thinking of making a Chocolate Tangerine Roulade (Gourmet 4/97)

for the Seder, using Kinneret "Whipped Topping" instead of the heavy cream. In addition to fresh tangerines/oranges the recipe calls for 3 Tbs. Triple Sec to be added to the filling.

Since 3 Tbs. isn't that much I'm sure I could substitute something else, but what? I have Passover brandy and have thought about reducing some fresh oj. Any thoughts?

Thanks.

OJ frozen concentrate....or your OJ reduction

Sabra liqueur? It's chocolate and orange flavor and kosher for passover.

You can substitute orange extract. The brandy is unnecessary unless you want a little taste of the alcohol.
