Given Steve Roud often posts here, I am a bit wary of referencing his book "The English Year", but there are 6 and two bits pages of customs on Good Friday, then a few on Easter Saturday, followed by another substantial section for Easter Sunday and Monday.

For Good Friday, he specifically lists Bread and Eggs, Burning Judas, Butterworth Charity, Hartfield Dole, Hot Cross Buns, Skipping, Tinsley Green Marbles, Washing Molly Grime, Widow's Son and Workington Football (listing the section headings).
