Ninja® Nut Butters, part #3

This post is about oil level testing of nuts.

Almonds have 78% fat content.  Trying to make almond butter with 1 tbsp. of oil created more of a soup than a butter.  I have been incrementally decreasing the amount of oil I use with blanched slivered almonds.  At 1 tsp., I was satisfied, but the finished product did not have the consistency of store bought peanut butter.  Therefore, I am attempting another round of almond butter using only ½ tsp. of virgin sunflower oil.

Unfortunately, I deviated from my own protocols.  While spinning the butter, I decided to go more with look and feel than any particular procedure.  The only thing I strictly kept to was 10-second bursts of the Ninja® to prevent it from burning out {although while sitting here typing this, I can smell the Ninja® in the other room}.  If one really wants to increase the frequency or batch size, one might consider a more powerful and, hence, expensive machine than the puny Ninja®.  All this said, I was a little surprised at the final result.
Not only is the product creamier than previous attempts, but it is also the most nut tasting of the butters I have made.  I surmise this is because the longer processing resulted in more of the essential oils being released, giving more flavor to the final product.  However, the consistency was more like a jam than a butter, as the picture demonstrates.  It is still spreadable, but not what one expects.  To see if the product will solidify, I vacuum sealed it and placed it in my kitchen cupboard, and I will check it in a few days to see if it butterizes. 

The above result has caused me to fret whether the failure of the pistachio butter a few days ago was the result of impatience.  Now, therefore, I will attempt the 72%-fat-content pistachio butter again but using 2 tbsp. of the oil, twice the amount as yesterday.
As the picture shows, it is a bit chunkier than the almond, though I think I have proved a few of my theories.

First, a nut with less natural fat must be primed with a larger amount of oil.  The sunflower oil is a good choice because it has very little flavor of its own.  The pistachio butter was very pistachio-y, if a little odd to the mind.  The almond butter was quite nutty as well.

Second, there is no one particular procedure that will produce consistent result across different nuts.  It took more pulses of the pistachio to get to the pictured result than it did for the almonds.  Had I not been an impatient person, I could have spun the pistachios more to get a smoother blend, hence proof of my abovementioned {yes, that is a word, and it even passes Word spell check!} impatience theorem.

Third, the Ninja® food chopper is probably the lowest end of tools that will accomplish nut butter making.  In fact, that is the very reason I purchased this device:  It was the least expensive machine which could make nut butter, albeit this claim was made by people on YouTube rather than the company itself.

The next steps are to see how the butter changes with resting and to create a chart of nut:butter ratios by experimenting with more types of nuts, including roasted.

POSTSCRIPT:  These two nut butters have been sitting in my kitchen cupboard for about 2 days now.  Both of them remain more of a nut jam than the peanut butter we have come to know and love.  This is still a usable product, as I had an almond butter sandwich last night.  However, don't expect Jif or Peter Pan to come out of the Ninja®.

Ninja® nut butters, part #2

Since the Ninja® Food Chopper is limited to two batches of nut butter per day without burning out, I performed the following two experiments.

This is my second batch of almond butter, using 1 cup of slivered blanched almonds but only 1 tsp. of sunflower oil this time.  I wanted to see the difference there might be between yesterday's batch and today's.

A tip on sunflower oil:  It does not solidify in the refrigerator.  I put it in the fridge yesterday to prevent rancidity, and when I took it out today, it was as clear as yesterday.  This is a good thing, as the smallest bottle I could buy was pretty large and my previous bottle went bad.  Now I know I can keep it in the fridge.

To proceed, then, I used the same technique I had used in my previous post.
Yesterday's batch {on the left} was definitely grainer than today's batch {on the right}, as you can plainly see.  Today's batch was also thicker, and the mouth-feel, including roof-of-the-mouth stickiness, was more like store-bought peanut butter.  I may do another blanched slivered almond test down the road to see if even less oil would work, but for now I am happy with this result. Therefore, it is on to the pistachios!
The first test of pistachio better was a failure.  As you can hopefully tell in the picture, the best I was able to achieve {even after adding 4 tsp. of oil} was a paste that looked more like pesto than butter.  This proves that each different nut will need a different amount of oil. I will try the pistachios again tomorrow starting with 2 tbsp. of oil.

That brings me to a mathematical point.  Will it be possible to calculate the amount of oil needed based on my few tests and an examination of the fat content of each nut?  It seems that almonds are 78% fat, while pistachios are only 72% and peanuts come in at 76% (Lagakos).  This may seem like a small amount, but cooking is chemistry; even a small amount can cause an explosion.  With this data, and the final amounts of oil used for each of the three different butters, I should be able to create a formula for how much oil to add based on fat content.

Well, back at it tomorrow with oil tests of almonds and pistachios.  I will have to wait for nut sales at Sprouts to do any other tests.

Ninja® nut butters, part #1

Ninja® Food Chopper nut butters, part #1

Some time ago, I was experimenting with making nut butters using a Ninja® Food Chopper.  This project took a back seat to other things that came along.  Today, I finally go ahead and start figuring out the particulars of making nuts butters using this device.

First, this is the Ninja® brand Food Chopper.  You don't need to acquire the entire Ninja® System if all you are doing is making nut butters.  The trick, I have discovered, is adding some oil to the mix.  The problem then becomes how much oil should be added.

My first attempt used 1 cup of blanched peanuts and 1 tbsp. of sunflower oil.  I ran the chopper in short bursts to chop up the nuts.  Next, I ran the Ninja® for about 10 seconds at a time, occasionally opening the chopper to scrape down the sides.  When I felt it had had enough, I poured it into a glass jar.
As you can see in the picture, particularly on my finger, this batch was still quite grainy.  However, I have come to accept this as a characteristic of homemade nut butters, as a Ninja® is not going to produce absolute smoothness and I am not going to run this through a cheesecloth or strainer just to get out those little bits.  Also, there was no string between my finger and the butter.  That indicates it was too liquid to stay in place, as peanut butter should.  Because it was too fluid, I cut the amount of oil in half for the second batch.
This batch used 1 cup of blanched peanuts and 1½ tsp. of sunflower oil.  We see that there aren't as many chunks left on my finger, and it was stiff enough to maintain a link between my finger and the butter. In my opinion, this is closer to a peanut butter, although not yet what I would like.

I also paid more attention to what I was doing, so I now have a procedure to follow to maintain the experiment.
  1. Place 1 cup of nuts and 1½ tsp. of sunflower oil in the Ninja® chopping chamber.
  2. Do 10 short bursts of the Ninja® to chop up the nuts.
  3. Run the chopper for 10 seconds, then allow it to rest for about 5 seconds.
  4. Perform the previous step a total of 6 times.
  5. Open the Ninja® and scrape down the sides of the chamber.
  6. Do the run and rest routine 3 more times.
  7. Open the Ninja® and scrape down the sides of the chamber.
  8. Do the run and rest routine 3 more times.
  9. Open the Ninja® and scrape down the sides of the chamber.
  10. Do the run and rest routine 3 more times.
  11. Scrape resulting nut butter into an air-tight jar.
I wanted to try another batch of peanut butter with a little less oil, but I did not have enough peanuts to continue, so I switched to blanched almond slivers.
Here we seen even fewer chunks on my finger and a more butter-like consistency.  It was the closest consistency there was to store-bought peanut butter.  This is what brought to mind that each type of nut might need a different amount of oil.  For example, using honey roasted peanuts will probably require more than 1½ tsp. of oil to perform properly.

Unfortunately, the Ninja® was beginning to smell like it was burning during the almond batch.  That means the device has a 2-batch maximum per day.  I will, therefore, have to put off performing any more tests until tomorrow.
