All butter shortbread with Sicilian lemonWhat goes into our organic lemon shortbread? …Aromatic organic lemons grown on the terraced groves of Sicily. Organic flour made with British wheat, including crops from Duchy Home Farm at Highgrove. Churned organic British butter. And the dedication of the family-owner bakery who have mastered that crumbly, melt-in-the-mouth texture. Each time you buy a Waitrose & Partners Duchy Organic product, sales from the brand provide a donation to The Prince of Wales's Charitable Fund. Since 2009, you have helped us raise over £30 million for good causes, supporting a wide range of projects and communities.
