ccasionally,I'll order in extra flavouring just to try a recipe & if I like the result I'll continue to stock those ingredients.Every once in a while though,I'll mix a recipe,find it tastes like vomit so I'll try chucking in a hefty lump of say Menthol to mask the base taste or only vape it with a pint of cider(to instantly wash away the taste)if I can still taste the base recipe under the menthol(but menthol is bloody fantastic at masking most evils)
