This Favourite Among English Jams Uses Two Types Of Strawberry: Sweet And Juicy Murano And Camarosas, Which Remain Whole During Cooking And Add A Pleasing Texture To The Finished Jam. Then To Add To The Excitement, We Stir In A Modest Helping Of FortnumS Champagne And Marc De Champagne, Which Together Add Both Flavour And Effervescence. ItS So Good That YouLl Want More - So We Poured It Into A Huge Amphora To Ensure That ThereS Enough To Go Round.
