going to show how i personally make cannarillos. remember there are a million ways to do things, this is just my way, and will likely evolve as i learn more.
i found a suitable length of hard wood 2 x 4,
drill a 1/8th inch hole straight through the center of where you want your cigar. ( i made two in one mold)
that is the hole for the bamboo skewer and also a pilot hole for the bigger drill bit.
next i drilled out the space with a 1/2 inch drill bit forming the body of the cigar. ( make it deep but not too deep)
then i sawed the 2x4 in half with a band saw.
and here it is
then we gather supplies
foil or parchment paper
fresh buds (i use the popcorn/airy buds) (you can use dry but i like using fresh)
clamp or vise
line the mold with foil or parchment, if using foil use dull side up.
grab some buds, remove stems and start packing it in there until you reach desired length
pack it in there real well.
repeat for the other half of mold. insert the skewer
align the mold and clamp tight.
let sit for a day or two the carefully remove the mold and you should end up with this
at this point, if you used fresh buds, you can choose to ferment, i believe we have a resident fermenter @ReikoX who could at least explain the process (edited, my mistake friend), (there is also a thread on it) or you can dry and cure. i use a vacuum sealer to sweat/cure to avoid the buds shrinking away from the skewer.
for the wrapping i use leaf i have pressed in a book for at least a month. longer is better. the i re-moisten by layering them with paper towels, placing in a ziplock bag, and adding 2 wet paper towels on top and bottom. seal and place in a warm place.
I'm waiting on my concentrate at the moment so I'll pause here, but basically i cover the "cob" in concentrate then wrap in leaves, reseal and wait..
