Has anyone ever noticed a bitterness in spinach/Spanikopita?
I've been asked to make Spanikopita without butter, using olive oil instead. Now the feedback is that there is a bitterness to the spinach, and I've only heard vague word of ways to get rid of that "bitterness"
Although I suspect the bitterness is due to the sole use of olive oil...
Has anyone else ever encountered bitter spinach?
