"Technically herbal teas are not teas- they are infusions. True tea is only the tea plant: camellia sinensis."

"All foods are fusion foods, because every time anyone runs into anyone from anywhere they adapt their dishes to new ingredients and new circumstances."

"Rosemary is often associated with memory because its scent lingers for so long."
