Traditionally this is a day to honour mothers and mother figures. In centuries past, it was a holiday when young people working as servants could visit their own mothers and often took a gift of food to share. As this day always occurred during Lent, a period of fasting, the fast was lifted on Mothering Sunday and a delicious Simnel cake was baked.
If you want to try making a Simnel Cake here are two recipe suggestions: I shall either use Delia's or Waitrose's -depending on which ingredients I can rustle up.
I'm thinking of my Mum, who died last summer, and the joy she had in our garden. Here she is collecting apples. What pleasure it gave her. I think I'll add an apple to the cake when I mix it.
