Hi! I love the piping of the meringue on top of this tart. Can anyone tell me what piping tip will achieve this (see picture)? Looks like a leaf tip? 

Thanks in advance for your help!

It is called a St. Honore Pastry Tip.

a leaf tip -- the kind that are just a smooth "V" cutout -- not the kind with the stem 

a leaf tip -- the kind without the cutout for the stem -- not the 67's -- the kind with just the smooth "V" cutout -- in fact i would do that with a cut cone --
