I was wandering through the internet and came across http://graphicalcooking.co. An attractive format, and I said to myself, "TikZ can do that!" And so it can. I wrestled with this this morning and have arrived at the following. My only problem is the lines connecting the hexagons in the instructions for the recipe. I cannot think of a way to get the various lines to intersect with each other (at the circled locations) without explicitly computing the distances. It would be nice to have a macro, \connect that would do the work, say, by use of the intersections TikZ library. Any suggestions? I hope I have commented the code sufficiently that there are no mysteries... I've included a couple of examples of what the as-yet fictional \connect macro might do.
