- Preheat the oven to 350°F. Line a muffin pan with paper liners (recommended). If you don't have liners, a good greasing of your muffin tin should be fine. 
- In a large bowl, combine the plant milk and lemon juice. Let sit for 10 minutes while you gather the other ingredients. 
- After 10 minutes is up, add the flour, cornmeal, sugar, baking powder, and salt to the bowl.  
- Add in the applesauce, oil, vanilla and lemon extracts. 
- Give it a good whisk until blended - there may be a few small lumps.  
- Last, fold in the blueberries using a spoon or a spatula. 
- Spoon the batter evenly into the prepared muffin pan, filling each cup almost full.  
- Bake for 30 minutes, until a toothpick inserted into one of the muffins comes out mostly clean (perhaps just a few crumbs).  
- Let cool completely before eating. Enjoy!
