Grinding Coffee Beans using Magic Bullet
I accidentally bought whole beans instead of grounds and was trying to use my "Magic Bullet" to grind the beans since I don't own a coffee grinder.
I have Starbucks House Blend coffee beans and a small Mr Coffee coffee maker.
About how many seconds is good for a decent grind?
If it works anything like blade-style coffe grinders, 6-10 seconds of pulsing should do it. You might want to give things a little shake between pulses so that everything gets in the action.
You sort of have to eyeball it -- depending on the efficiency of the blade, it may take more or less time. The trick is to get the beans all ground to a fairly consistent size -- you want to avoid pulverizing some beans into dust, while the rest have are too coarse to do any good..
The coffe hounds will tell you that a burr grinder is superior, but fresh-ground coffee (even if not done the "best" way) is way better than pre-ground.
I use my magic-bullet to grind beans all the time in my vacation home. It depends on how many servings I am making. Best to just watch it, 5 seconds at a time, pick it up off the base and shake it and see what it looks like, if it's not fine enough for your machine push it down for another 5.
I don't usually make pots of coffee, just 1-3 mugs at a time using my Aeropress. The Aeropress calls for a lot of coffee, about 1.5 tbsp per mug.
I think I used about 5 tbsp of beans the last time I made a pot in the drip machine. It took a long time to grind, and I was worried about them getting too hot. I think grinding two smaller batches might be better.
One of the reasons people like burr grinders is they don't heat the beans as much. The other reason is to get a consistent grind to get the pull time right when making espresso.
