This time, I wanted something a little different, so I combined our favorite Mexican spices with a bit of brown sugar and a little oil to create a rich coating that sealed in the moisture and kept this roast juicy and tender with loads of great flavor from all the spices. Given two thumbs up by the whole family, this roast was a huge hit for dinner this week. One of my boys is opposed to spicy heat in almost all forms, so I made sure to give him pieces with minimal spicy coating on them. However, he still voted it a success, spices and all.
