Rescuing white veal stock

Recommended Posts

StevenC   

When a white veal stock ends up too dark and opaque, is there a way to rescue it and remove some of the discoloration? Perhaps by clarifying it with some ground veal and egg whites, like you'd do for a consomme?

Some background: I've been going through a bit of a classical French phase for the past few weeks, and having recently come upon a great source for veal bones, I've been venturing into making white veal stock as a basis for some classical sauce experiments. I made my first batch last week, and it turned out perfect. I used bones and shanks of uniform size with a split calf's foot, blanched everything according to the guidelines in the French Laundry cookbook, replaced the water, rinsed everything, and then cooked it at 170 degrees F for 8 hours. The stock was clear, with a wonderful golden color and great body, and had an almost custardy aroma. Totally different from and much more subtle than white chicken stock.

Anyway, last night I made a bigger batch with larger, unbroken shank bones, among other things. I sensed I was in for trouble when the bones threw off so much blood during the blanching phase that the water turned bright crimson and then dark brown-gray. I threw out the blanching water again, rinsed the bones, and started the stock, but I think the larger bones continued to throw off raw blood into the stock, darkening the end product. Also, I cooked the stock at a lower temperature (160) this time for ten hours--perhaps not hot enough for the proteins to coagulate out of the stock? I was surprised at how little scum rose to the surface throughout the entire process.

      At this time of year when you can hoard fresh, local strawberries because they are so abundant, why not freeze them and enjoy them all year long. Then you won't have to buy tasteless, fake looking ones in the dead of winter!

      The best way to preserve them, sugar-free, and have them fresh, year-round is to freeze them. Remember to start with the freshest strawberries possible. Strawberries start to lose freshness and nutrients quickly and will only last a few days in the fridge, so the sooner you freeze them the better. Follow these steps and they will last up to a year in the freezer:
      1. Gently wash them and pat them dry or allow them to air dry for an hour or so. Slice off the tops, including the stem and any white area, then cut them in half lengthwise.
      2. Line one or more rimmed baking sheets (depending on how many berries you have) with parchment or SilPats. Arrange them in a single layer on the sheets. and place them, uncovered, or loosely covered with plastic wrap in the freezer. Allow them to freeze solid, about 12 hours. Once frozen, transfer the berries (they may stick to the parchment a bit, but peel off relatively easy) to a freezer weight plastic zipper bag. Press out as much of the air from the bag as possible before sealing, to minimize freezer burn over time. If you are planning to leave them in the freezer for months, then consider double bagging them. Place the bagged berries in the freezer, where they will keep for up to one year.
      Note: I will warn you that the thawed berries will not be firm and bright like they were when raw and fresh. They tend to thaw out a bit mushier, and slightly darker…but can still be used for anything you would use fresh strawberries for. For smoothies, use frozen.
      Optional: Brushing the berries with a bit of lemon juice before you freeze them will help to preserve their color. While strawberries can be frozen whole, cut or crushed, they will retain a higher level of their vitamin C content if left whole.

      My Breville BSO 800XL  just died on it's second birthday, after only *extremely* light use at my beach house.  Just won't power up.
       
      Reading online, I learned that a common failure mode is the thermal fuse blowing -WHICH IS DESIGNED TO BLOW AT <450F.  This is a $3 part at Radio Shack, and there is a detailed instruction on how to replace it here:  http://virantha.com/2014/03/02/fix-your-breville-smart-oven-by-replacing-the-thermal-fuse/
       
      So I guess I'll give fixing it myself a try and report back.  Has anyone here done this repair?  Was it successful?  And why would Breville use a fuse that is lower than the appliance's top heat settings?
       
      Thanks!

      Greetings,

      I've cooked several recipes from Keller's "Bouchon" the last couple of weeks, and have loved them all! At the moment (as in right this minute) I'm making the boeuf Bourguignon, and am a little confused about the red wine reduction. After reducing the wine, herbs, and veg for nearly an hour now, I'm nowhere near the consistancy of a glaze that Keller specifies. In fact, it looks mostly like the veg is on the receiving end of most of it. Is this how the recipe is meant to be? Can anybody tell me what kind of yield is expected? Any help would be appreciated. Thank you, kindly.

      I've had an idea flowing across my brain waves over the last few months. It's on every channel and I'm getting ready to pull the trigger. 
      I'd like to try to braise a dish in my smoker. I am thinking of braising a rabbit, but the I'm not looking for guidance on the protein/ingredients, rather the technique. I turn to you, o internet, in hope you will tell me your secrets.
      Has anyone ever braised in their smoker before? I've done some research, but I haven't seen much on the "how to" for the technique. Here's my plan:
      - Brown the rabbits on skillet (stovetop)
      - Get the aromatics/other stuffz sweated browned, etc.
      - (MEANWHILE) Smoker heats up to 300-325 degrees.
      - Add stock to rabbit, bring to a simmer on the stove top.
      - Transfer to smoker, braise uncovered for 1-2 hours, then cover with foil to finish for as long as necessary.
      I've seen folks smoke and then braise, but I haven't seen much on the idea of braising something IN the smoker. I saw something on CookingwithMe.at about doing something similar with pork belly, but that's about it.
      All I know is that after using stock+drippings from a smoked turkey created this CRAZY MIND-BLOWING flavor, so I'm basing this a lot off that idea.
