Knife Sharpening

Over the years, I have acquired numerous sharpening and honing devices: whetstones, carbide rods in holders, diamond stones, and more. While the carbide “pull it down the blade” sharpeners work, they do no produce an edge that lasts. Invariably, I keep returning to the whetstone.

But I loathe using the stones, probably because I’m not very good at it. It takes me a half hour per knife to get something resembling that super-sharp factory edge. Because it takes so long, I don’t sharpen them often enough. So I start using the santoku knife instead of the chef knife, and a carving knife instead of a paring knife. Until there’s not a sharp knife left on my magnetic knife bar.

Then, finally, I spend a half day sharpening all my knives. Which I did, last week. And by jove, they are much sharper. But it’s also obvious which ones I didn’t spend enough time on. My chef’s knife no longer glides through raw carrots like it did 15 years ago when it arrived from the Henckel factory. And I lack the sharpening skills to get it there.

I considered hiring a service to sharpen them all, setting the edge for me. Then I could continue touching them up with the stones. But for the same money, I found and purchased a knife sharpener. My review is on Amazon’s site.

Kitchen Math: Area

Q: Your pizza dough recipe is for a 12″ diameter pizza. Your pizza pan is 14″ diameter. You proceed by:

a) make a thin crust pizza
b) scale the recipe by __%

I chose to scale the recipe. A twelve inch pizza pan has an area of 6 * 6 * 3.14 (π) = 113. A fourteen inch pan has an area of 7 * 7 * 3.14 = 154. The difference in area is 154 – 113 = 41. Since the existing recipe is for 12 inches, I need to scale it up by 41 / 113 * 100 = 36%.

MacBook Pro sleep causes network failure

A short time ago, my MacBook Pro developed a new and annoying habit. After putting it to sleep by closing the clamshell, and then waking it, the WiFi network wasn’t working.

Safari would report “You are not connected to the Internet” and DNS queries via dig in Terminal would fail with an “Unknown host” error message.  Interestingly enough, ifconfig reported that I did in fact have an IP address:

en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500

ether 60:33:4b:XX:YY:ZZ

inet6 fe80::6233:4bff:fe0a:d552%en1 prefixlen 64 scopeid 0x5

inet 10.0.1.43 netmask 0xffffff00 broadcast 10.0.1.255

media: autoselect

status: active

And netstat reported that I had a default route which pointed at my default network gateway:

$ netstat -rn

Routing tables

Internet:

Destination        Gateway            Flags        Refs      Use   Netif Expire

default            10.0.1.1           UGSc            7        0     en1

10.0.1/24          link#5             UCS             4        0     en1

Upon further examination, I was also able to ping the default gateway. And I was able to send DNS queries (dig example.com. @10.0.1.1 syntax) to the gateway and get them resolved. But attempts to resolve hosts using Snow Leopard’s DNS recursion failed.

The workaround was turning WiFi off and then back on. Voila, problem solved until the next time I put my laptop so sleep. Today I decided to find and fix the problem. The solution was disabling IPv6 support on the WiFi network interface (in Network control panel). Voila, problem solved.

 

The Joy of Cooking – redux

After a multi-year hiatus, I have resumed my quest to to cook my way through every recipe in Joy of Cooking. Notable things I’ve learned in the past few weeks:

  • I like tomato sauce. This greatly surprised me, as I’ve had no special affinity towards foods with tomato sauce. What I learned is that I don’t dislike tomato sauce, I dislike Prego, Ragu, and other ‘canned’ tomato sauces. When made fresh from raw ingredients, I like tomato sauce. I really like it.
  • I learned how to make a good puffed pastry. The secret is persistence. Just like with making bread, accept that the first few times will end in disappointment. So start with something like an apple turnover, so even a disappointing result is good.
  • (My) kids don’t like soups. It don’t recall liking them much as a kid either, so I shouldn’t be surprised. But I’ve found a greater affinity towards them in my middle years.
  • Kids love, love, love familiarity. I’ve made a dozen types of pancakes and several were excellent. But they still prefer “my” whole wheat banana buttermilk pancakes.
