This bean is missing the classic green banana astringency present in most cocoa beans when raw. Because of this you are both able and want to keep the roast light....but you also need to make sure it is roasted fully or you run the risk of not developing flavors. On the flip side, if you take it too deep you run the risk of turning the nut flavors excessively bitter and making the whole profile harsh and unbalanced.
I mentioned this is not for novice roasters. You really need to roast by smell and back off the heat whenever you find it getting sharp. You need to treat this beans with kid gloves. What that means is at least a 3 minute development phase and 3:15-3:30 is better. You then need to slow the roast down even more and eek out at least 2 minutes in the finishing phase and 3 minutes would not be amiss but don't take to too long or you hazard dulling the flavor. And through all of that, you really don't want to get much above 246-248 F EOR.
Profile Drum Roasting: The lighter profile I ended up with was 15:45/18:45/20:30 @ 240 F. The higher one was 13:20/15:10/19:15 @ 254 F and I think although interesting was a little higher than it should have been.
Behmor: I really don't recommend using the Behmor unless you have a thermocouple probe in it. There is just too much variability and this bean doesn't signal by aroma as you need. If you do have a probe, use P1 profile until 170 F and then P3 Manual mode (50% power) until 222 F, then down to P2 until 240-245 F. Kid gloves I tell you.
Oven Roasting: You will need an IR thermometer. Roast 2 lb of beans. Preheat your over to 325 F. Place your cocoa beans in a single layer on a baking sheet and into the oven. Stir the beans at 5 minutes and check the temperature. Continue roasting until the surface temperature reads 205-215 F (it may well vary across the beans). At that point, turn your oven down 10-15 F above your target EOR, in this case 240 + ~15 = 255 and continue to roast, stirring every 5 minutes until approximately 245 F. Again, there will be variation but the beauty of this method is having turned the oven down it is difficult to over roast. The important part here is to get good momentum going in a hot oven and then basically coasting to finish. You may not get much chocolate or brownie aroma with this one.
