Your blog has the most interesting recipes on Hive. Have you considered writing a travel-and-recipe book and self-publishing on amazon?
Chia seeds are full of health benefits. Also, flax seeds are another non-traditional podi ingredient that are healthy and work well. Once upon a time I wanted to publish an e-book, but our current living situation doesn't grant us much free time.
Once back in Cambodia, I think our creative freedom will blossom again, and I hope to publish an e-cookbook. Thanks for your kind words.
