More that one ay to shape a cookie!
A suggestion for the recipe "Oat and Raisin Cookies", https://www.deliaonline.com/recipes/collections/biscuits-and-cookies/oat...
As presented the mixture is rather dry, and hardly sticks together to form the walnut-sized balls. I added another egg, now one can make the balls as suggested.
It's horribly sticky on the hands, so I pressed some (about 32g) into an espresso cup with a thin teaspoon. The cup should be narrow at the bottom. Extract the mixture by pressing the tip of the spoon between it and the inside of the cup, then pull both out. Place the flat top of the roughly hemispherical mixture on the baking sheet, and press it down lightly. The method is much less messy and faster than that suggested in the recipe
