Of the myriad baked goods that my mother-in-law makes for the holidays, these simple cookies are my favorite. Well, maybe it’s a tie between these, carrot cake, ginger molasses cookies, and coffee cake. We are visiting her in Massachusetts this week, and I made sure to note the technique. She reminisced with me about all the showers she’s attended, where a group of women would roll out the knots and ice the cookies around a big table. You can find these in any Italian bakery worth its salt, but making them for loved ones is extra special.
