The tradition of eating pancakes on Shrove Tuesday has been around since the 15th century, when certain produce, especially perishables like eggs and butter, had to be used up before fasting began a day later in Lent. Saying that, anything else could go in, therefore, pancakes could possibly be made with anything, not just eggs, butter and flour.
And I like that idea a lot.
Hence, I had an idea of spicing up my pancakes a bit and, when researching for savoury pancake ideas, I could see I was not the only one.
