Unlike raw chocolate made with coconut oil which melts at room temperature (around 25C/77F), these chocolates will stay set at room temperature. That means they are portable and can be kept in the pantry. If you are expecting a heatwave over 35C (95F) then, just like you would with any old regular blocks, pop them in the fridge. Raw cacao butter can be found in most health food stores - I use the Loving Earth brand. Other things you could add include chia or other seeds, chopped nuts, organic shredded coconut, dried fruit, vanilla protein powder, raspberry jam or zest from an orange.
