Treant nuts - Pecans are preferred, but whatever the treant will give should work. It's probably best to avoid stealing.
2 cups Astral Sugar (sugar)
1 cup Grove Water (water)
1 cup Razorback milk (milk, heavy cream works better) - If you are feeling daring or want a practical joke you can use Troll Carrion Cream
Chocolate - Try to avoid the ancient type.
First you have to make caramel. Start a campfire and put Grove Water in a pot. Poor all the Astral Sugar into the pot in the middle. Avoid stirring, it will do most of the work for you. Put the pot over the campfire and wait until the sugar dissolved. It will start to turn brown eventually. Once it starts to turn brown, slowly add the milk/cream and be careful because it will foam up. Continue to stir it until it thickens and take it off the heat. It will have to cool for a bit before the next step.
Next you want to find something flat to make your candies on. A Rock, treant bark, leather skins, doesn't matter as long as it's flat. It also works better if it has something on it that makes it less sticky. Shambler mucus works well for the situation. Arrange your nuts in appropriate shapes for your seacaps and shamblers. Poor the caramel over the nuts. You may have to do a little smushing or reorganizing to make sure all the nuts stick together and maintain roughly the shape you want. If the caramel wont work, warm it up just a little. Let them set for a bit while you work on the next step.
Take one pot and fill one with water and put it over the fire. Smash/cut up the chocolate into little pieces and put it in a bowl or another pot. Put the container with the chocolate over/in the pot with the water and stir it until it melts completely. Poor the chocolate over the caramel/nut bunches. It will need to set for a while. They will be edible faster if you can find a way to cool them down quickly. Iron Pine Peak would probably be a great place to make these so you can set them out in the snow.
Congratz! You have delicious Chocolate Caramel Seacaps and Shamblers. They taste a heck of a lot better than the real creatures.
