Add cranberries, pear, ginger, rosemary leaves, maple syrup, and water in a medium saucepan. Cook over medium-high heat, occasionally stirring until the mixture starts to boil and the cranberries burst open approximately 5 minutes.
Reduce heat to medium-low and simmer for another 5-10 minutes. While cooking, mash the cranberries and pears with a wooden spoon. Season with a pinch of sea salt and stir to combine.
Remove from heat and allow the sauce to cool for 15-20 minutes before checking the consistency. Add a little water if the sauce is too thick. Taste and add more maple syrup for a sweeter sauce, if desired.
Optional: For a smoother sauce, blend one-half of the cranberry mixture in a food processor or blender until smooth. Stir puree back into the remaining sauce before serving.
Serve immediately or chill before serving. Enjoy!
Notes
Choosing the Right Pears: Choose ripe but firm/hard pears for the best results. Overripe pears can make the sauce too sweet and mushy. Bartlett pears or Anjou pears are ideal for this and many pear recipes.
Adjusting Sweetness: The sweetness of your sauce will largely depend on the ripeness of your pears. Taste your sauce before adding the maple syrup, and adjust the quantity as necessary.
Leftovers: This pear sauce can be stored in an airtight container in the fridge for up to one week. It can also be frozen for up to 3 months and thawed in the fridge before use.
Blending: If you prefer a smooth sauce consistency, you can blend the entire sauce instead of half. If you like a chunkier sauce, simply skip the blending step.
