Original Recipe taken from A Proper Newe Booke of Cokerye, (of the sixteenth century) (page 19) edited by Edited by Catherine Frances Frere, found in A Collection of Medieval and Renaissance Cookbooks compiled by Duke Cariadoc of the Bow and Duchessa Diana Alena:
To Make Pyes .... yf you wyll have paest royall, take butter and yolkes of egges and so tempre the flowre to make the paeste.
My Translation:
To make pies .... If you will have paste royal, take butter and yolks of eggs and so temper (i.e. mix with) the flour to make the paste.
My Interpretation:
1 cup flour
⅓ cup butter
2 egg yolks
2 to 2½ T water
Cut butter and egg yolks into flour until crumbly, add water and knead mixture until it forms a ball of dough. Roll out dough then place into pie pan.
