Chilling is crucial for clean spirals and minimal spreading, so keep the dough and logs cold and work with one at a time; if the dough softens, pop it back in the fridge for 10–15 minutes. To prevent gaps, roll tightly without squeezing out filling, and use a sawing motion with a very sharp knife for clean slices. For a brighter strawberry flavor, use a thick, good-quality seedless jam or reduce looser jam over low heat until spreadable. You can swap strawberry jam for diced macerated strawberries that have been drained well and tossed with a little cornstarch. For make-ahead convenience, freeze the filled logs up to 2 months, thaw in the fridge until sliceable, then bake from chilled.
