Lemon Shortbread Slice

Makes 12-14 pieces Prep Time 10 minutes   Cook Time 20 minutes   Rated:

I do love a sunshiny, lemon slice any time of year...add in the rich shortbread base and I am in heaven. I hope you love these as much as I do! The best trick ever (by the way) is to add the tiniest little bit of turmeric to get that real sunshine yellow going; There is really no flavour from the turmeric because the amount is so minute, but the colour just makes you so happy to eat it! (I am always happy to eat anything lemon...but I digress...)

I think this slice is the perfect antidote to a wintery afternoon. Cue the chamomile tea, get out your prettiest china plates and you are in business.
