Rinse strawberries and dry thoroughly. Use a syringe or clean marinade injector to inject about 2 teaspoons of brandy into each berry. Place them on a baking sheet, and refrigerate for about 30 minutes.
In a metal bowl over a pan of simmering water, combine bittersweet chocolate and shortening. Stir occasionally until melted and smooth. Stir in heavy cream and 1/4 cup of brandy. Place white chocolate in a separate bowl, and when the dark chocolate has melted, place the bowl of white chocolate over the pan of simmering water, stirring occasionally until smooth. Be sure to remove from heat as soon as it is mostly melted, white chocolate can be sensitive.
Dip strawberries into chocolate, and let the excess drip off into the bowl before placing on waxed paper to set. When the strawberries have all been dipped in chocolate, dip a fork into the white chocolate, and drizzle back and forth over berries to stripe.
