Failed attempt!

Yesterday I tried to make Maple-Raisin Almond Butter, but I failed. I don't know what I did wrong... so please nut butter experts, take a look of how I made and tell me what I did wrong!!!
I used about 1 oz. of raisin, 1/2 pounds of roasted almonds and 1 tbsp of maple butter Half way through of the grounding I added raisin and maple butter. Continued with the grounding for another 10 min. I remember last I made almond butter, by then, it began to release the fat and formed the butter. But yesterday, no matter how long I grounded, I couldn't have the butter consistency that I wanted. So, end product: not butter definitely, although it is delicious!
Any thoughts about my failure?

okay. the rest of my day (not exciting at all). For the first time in years I woke up by the alarm at 7am. I had to go to school to proctor a final exam so no time for a proper breakfast. Just two toasted WW bread with LC and homemade almond butter. Oh... the reason of my sleep in was a movie that I watched the night before called " Nothing but the Truth". It's really really good, watch it if you have the chance. It's drama I think... not the easy kind of movie, but very deep and insightful.
Anyway, back home around 10.30, I had my second part of the breakfast: another toast with LC and an apple. And a cup of powdered soy milk. A shouting out of my new watch (gift from Star)
Blogging and finishing the spread sheet about food nutrition for Dad, I had a yummy lunch. I used the fillet I bought in Costco, marinated with cooking wine, soy sauce, miso paste and a korean chili paste, sesame oil, sesame seeds and brown sugar. Baked it for abour 20 min. As side dish I had cherry tomatoes and a sauteed cucumber with mushrooms and spinach. DELICIOSO!!!!!
Dessert: 1 min pumpkin cheesecake = 1/4 c. cottage cheese + 1/4 c. greek yogurt + 1/4 c. pumpkin + cinnamon + pumpkin spice Then, the funniest part of my day began: GRADING (82 exams). It took me almost the ENTIRE afternoon. When I was done with it, I felt needing some kind of workout! So I did 60 min flow yoga at home and walked around the neighbor with Qiao another hour.
PM snack was greek yogurt + blueberries (from Costco which wasn't as good as organic ones, not sweet and tasty enough) + wheat berries. And a gigantic grapefruit from Costco which was sweet and juicy. Dinner had to be quick (I came back from the walk at 8.30pm). So I had another sauteed romaine with chili flakes; scrambled egg with 1 gigantic red pepper; millet porridge. Although it was simple, I really enjoyed it! Sometimes I'm so easy to please! ^_^
Dessert: white fungus drink + blueberries cheesecake.
Question: Have you made nut butter? How was your experience?
