What are your go-to non alcoholic but a bit fancy drink??
I have found some non/ low alcoholic, low carb alternatives for when I want a refreshing drink but don’t want to ‘drink.’
My go to is soda water or chilled water to start with then I add a splash of lime juice, apple cider vinegar or bitters. You can add these by themselves or combine them. I think Carl mentions a similar drink but he adds some stevia and finds it imitates a cider. I find the drinks refreshing and the acidic/ bitter flavours make me feel like I am drinking something more that an non alcoholic drink.
For something a little lighter I add rosewater to my soda water. This also goes well with some freshly squeezed lemon juice and you could add sweetener.
Then there are the classics- mint, other herbs etc. I think you could make a spiced infusion with cinnamon etc or have iced tea.
