I just did an afternoon tea at church for 100.
i had -
triangle sandwiches - cucumber and apple, ham with mustard butter, smoked salmon and cream cheese
finger sandwiches - egg mayo with rocket, cheese and chutney, hummus and grated carrot
All crustless (made with that crustaway bread), you get 4 triangles or 3 fingers from 2 slices of the bread and made with real butter.
Sweet - scones with strawberry jam and cream, pancakes with honey butter, selection of sliced cakes - plum cake, banana loaf, date and walnut cake, madeira cake, cinnamon loaf, cup cakes and mini Victoria sponges
2 types of tea and coffee - no booze because we aren't allowed in our church.
