I thought I would try baking Canneles de Bordeaux using Melon flavor Rum. But ... I should have stayed with the Dark Rum. Tonight's testing was to bake test with melon flavor rum, and using silicon baking mold. Even though I do not have a "silicone Canneles molds", I improvised the regular silicone baking mold to test.
The baking result: The copper canneles molds are still the best. The aluminum canneles molds did a good job. The silicone baking mold did not caramelize the outer part of the Canneles as copper and aluminum molds did. But, it turned out interesting, I think.
Taste testing: The Canneles baked in silicon mold's outer shell did not pass the Canneles' egg shell crunchiness. Even after 1 hr 40 min of baking, the caramelization is not 100%. The texture is chewy.
I made petite canneles rather than the usual demi size because I wanted to quickly bake and find out the result.
