There's actually a full-size and a dwarf-size Meyer lemon tree. Mine's the dwarf version, and so far, I can easily reach all the fruit!
Mar - try scratching the rind a little bit and sniff it. Meyers will smell a bit more floral (to me, anyway) than regular lemons--not as "sharp." Another clue is when you cut into a Meyer, the inside will have a little more orange color to it than a regular lemon. Anyone else have ways of telling which is which (besides taste, of course)?
Vanilla beans are easy, and boy--do they have great flavor!
I buy mine online from Beanilla.
FYI, I didn't can this marmalade--just put it into jars and giving most of it away. According to the recipe it'll be good for two weeks, so I put a "use by" date on the label. It's probably safe longer than that, because of the amount of sugar and acid, but I'm no expert and wouldn't want anyone to have an issue.
