It is interesting to see how our perception of flavours change over time. Not that long ago chocolate was considered almost exclusively a sweet flavour, now increasingly one can find chocolate in savoury recipes. Maybe it is the Mexican influence on our cooking.
We recently took on a Stevia chocolate with coffee and cardamom that tastes great. Though we use cardamon in spice mixes for curry, it can also be used in rice pudding and I have had some delicious Swedish cardamom buns. .
Some flavours travel the other way; from savoury to sweet dishes. It now seems that you can have chilli sweets and a lot of ranges have chilli chocolate but I have not seen any stevia chilli chocolate in the UK yet. I know some restaurants have desserts featuring basil ice cream but no one seems to have developed a basil flavoured sweet. I wonder why not, it could be popular?
