I'd say endothermic because the temperature went down, meaning energy was absorbed and then when the temperature went up again, the substance the absorbed the heat had melted and warmed up again. It's like when you put ice in water, it absorbs the heat of the water and melts, lowering the water temperature, but only until the ice has melted, then the water stays cold for a while before returning to room temperature. I know this because in an exothermic reaction, heat is given off, but in an endothermic reaction, heat is absorbed.
