Grandma's Butter Bowtie Cookies

Prepare ingredients:

• 1 pound (450g.)sweet (unsalted) butter,
• 1 cup (240ml) sugar,
• 4 hard-boiled egg yolks, finely crumbled,
• 4 ½ cups (1050ml) white flour,
• 1 ½ teaspoons (7ml) vanilla extract.

Thoroughly mix the butter, sugar, egg-yolks and vanilla extract, then slowly mix in the flour and knead. If the mixture appears to be too liquid, add a little flour. 

Place the kneaded ball into the refrigerator for at least 2 hours.

Roll out the mixture on a board until about ¼ inch thick (about 7mm) - this is the thickness of a standard pencil. 

Cut strips about ¼inch wide (12mm) and 6 inches (150mm) long, and twist into a figure-eight, like a pretzel. 

Break an egg, and smear the bow-ties. Sprinkle with colored sugar. (Alternatively, you may sprinkle with poppy seed instead). 

Place on baking tray and insert into oven preheated to 400°F (200C) for 20 to 25 minutes. 

Watch carefully towards the end as the cookies burn very easily.
