Every time I make them in my kitchen I'm reminded of baking with my grandmother who taught me all the little tricks to get them just right.

Pro Tips for Success
After making these countless times I've learned that measuring flour correctly makes all the difference. I always spoon it into the measuring cup and level it off for the perfect texture. A little trick I discovered is warming the jam slightly it makes filling those thumbprints so much easier.

I love arranging these on my grandmother's vintage platters for special occasions. Sometimes I'll make an assortment with different colored jams it looks so festive. They're perfect with afternoon tea and always the first to disappear at cookie exchanges.
Storage Tips
These cookies keep beautifully in an airtight container I just make sure to layer them between parchment paper so they don't stick. Sometimes I'll make extra dough balls and freeze them it's so nice having them ready to bake whenever a craving hits.
Customization Ideas
My family has their favorite variations. My kids love when I drizzle chocolate over the tops and my husband's partial to orange marmalade in the centers. During the holidays I'll dust them with powdered sugar it makes them look like they're topped with fresh snow.
