In a small bowl, mix together garam masala, paprika, ground cumin, sea salt, coriander, sugar, ground turmeric, and cayenne pepper.
If you have time, heat coconut oil in a pan over medium heat. Sauté the finely chopped onion until translucent, about 3 minutes, then add minced garlic and fresh ginger.
In the slow cooker, add diced potatoes, chickpeas, frozen peas, chopped bell pepper, jalapeño, tomato purée, fire-roasted tomatoes, and the spice blend.
Cover and cook on High for 4 hours, or until potatoes are tender.
While the curry cooks, soak cashews in water for at least 20 minutes. Drain and blend with 3/4 cup of water until smooth and creamy.
Once cooking is up, stir in the cashew cream and lemon juice. Adjust seasoning before serving.

Optional: Garnish with fresh cilantro before serving.
