Substitute for Berry Liqueur, Cassis

[wintersummer]

I'm making Gourmet's "Berry Tart with Mascarpone Cream". One ingredient is "2 tablespoons dark berry liqueur such as blueberry, blackberry, or cassis"

Any thoughts on what I could substitute? I really don't want to purchase liqueur for only 2 tablespoons.

Thanks.

If the purpose seems to be the berry flavor, maybe a couple tablespoons of jam. I would be tempted to use amaretto or a nut liqueur if I had it on hand, although brandy or sherry might be delicious too.

The juice from frozen strawberries, or blend berries and strain them for the liquid
Also, most gGrocery stores sell cherry juice or grenadine syrup down the non-alcoholic mixers aisle.

Do you have any Vodka? You can force fruit through a strainer and reduce it over low heat, then add a small amount of Vodka.
