Step 1In a large saute pan over medium heat, cook the onions and garlic until the onion is translucent, 3 to 5 minutes.
Step 2Stir in the tomato puree and chipotle pepper and bring to a simmer over medium heat. Continue to cook for 15 minutes, stirring occasionally, to allow the flavors to blend and the sauce to reduce slightly; lower the heat if the bottom of the pan gets too hot so the sauce doesn't burn.
Step 3Remove the pan from the heat and whisk in the cream, then set aside. Makes about 1 1/4 cups sauce.
Step 1In a medium saucepan, combine the jamaica flowers with 4 cups of water over high heat and bring to a boil. Reduce the heat to a simmer, and simmer the flowers for 30 minutes to rehydrate completely. Strain the flowers, then allow them to cool to room temperature. Finely dice and set aside.
Step 2In a large saute pan, melt the butter over high heat and add the onions. Saute, stirring frequently, until the onions are translucent. Reduce the heat to medium and add the diced flowers, zucchini and bell pepper, stirring occasionally and cooking until thoroughly warmed. Season with 1 teaspoon salt and one-fourth teaspoon pepper, or to taste. Set aside in a warm place.
Step 3Reheat the chipotle sauce in a medium saute pan over medium heat until warmed, stirring frequently. The warmed sauce should be pourable; if too thick, add just enough water to thin to the desired consistency. Keep warm.
Step 4In a medium saute pan, combine the oils and heat until a thermometer inserted reads 360 degrees. Dip the tortillas into the oil, one at a time, for just 1 second to warm through, then remove to a paper-towel-lined tray to absorb the excess oil.
Step 5To assemble the enchiladas, spoon one-half cup filling into the center of each tortilla, then roll the tortilla to form an enchilada. Place two enchiladas onto a plate for each serving, and divide the warmed chipotle sauce evenly over each serving. Spoon 2 tablespoons of sour cream over each serving, and sprinkle over 2 tablespoons crumbled queso fresco, or to taste. Serve immediately.
