Butter Tart Sauce
 In small pot on stove top, add vanilla and cream, heat, then add butter.
In a separate bowl, combine egg, and brown sugar. Add egg mixture to warm cream mixture and simmer on low, then add vinegar and cornstarch.
Keep whisking until thickened on med-low heat for about 10-15 minutes. It should be the consistency of gravy.
Remove from heat and add raisins. Set aside to cool and after 10 minutes refrigerate until ready to use. You can reheat the sauce in the microwave before serving.
Garnish
Garnish waffles with butter tart sauce and whipped cream and additional raisins, as desired.
