Add Dairy Milk (FLAVRZ) @4% to have more a milk base ice cream flavour.
Add Popcorn (FLAVRZ) @ 2%, Shortbread (FLAVRZ) @0.5-1%% & Sponge Cake (FLAVRZ) @ 3% to get a waffle cone. You can try also Strawberry Biscuit @ 1-2% though you may need to increase the rum & raisin by 1 or 2% to stop the strawberry coming through.
Golden Syrup (FLAVRZ) will add more richness to the rum and also Tobacco #37 (FLAVRZ) @0.5% will add more depth to the RUM.
Yes I know it is a tobacco flavour but it does work.... or drop the vanilla swirl out and increase the Vanilla Ice cream to 12% and add in 1% of Bourbon (FLAVRZ) to get more rum.
