Pour the cream into a tall saucepan and heat over medium-high heat. Reduce the cream by half, approximately 5-7 minutes (the cream will foam significantly—watch carefully to prevent overflow).
Reduce the heat to medium. Add the curry, vegetable stock, raisins, pineapple, diced chicken, and minced garlic. Cook for 5 minutes, stirring occasionally, until the chicken is cooked through (internal temperature 74°C / 165°F).
