"Making your own sugar cubes is economical and fun, plus they make great homemade gifts! Wrap them in a cellophane bag tied with a pretty ribbon and you'll delight every coffee and tea drinker you know."
Stir sugar, espresso, water, and espresso powder together in a bowl with a fork until all the liquid is incorporated and the mixture has the consistency of wet sand. Pour mixture onto a baking sheet.
Press sugar mixture by hand into a firmly-packed rectangle. Straighten the sides of the rectangle with a dough cutter or metal spatula. Cut mixture into small cubes and spread cubes slightly apart on the baking sheet. Dry cubes at room temperature until set, about 24 hours.

Be careful not to add too much liquid or the sugar will begin to dissolve. Air drying your sugar cubes takes longer but is more reliable than baking them, so be patient!
