chestnut puree quantity

Question

My recipe called for 250g of chestnuts, blended with 125ml of cream and 125ml of milk that you then blended together to make a puree. When i went to the supermarket I discovered they had tinned "Chestnut puree" so I grabbed that instead I am now wondering how much of that I should add ?

Answer

Assuming the chestnut puree is just chestnuts, well, use 250g of it.

If it has other ingredients... I guess you'll have to try to figure out how much of them. You might be able to deduce it from the nutrition facts and the nutritional content of the chestnuts themselves, especially it's just chestnuts and water.

Edit: To be clear, I'm telling you how to replace the chestnuts. You still need the rest.

Given that it's chestnuts and water, it's trivial to figure out how much of it is chestnuts. (It would be difficult if there were other ingredients providing nutritional content.) Just use enough paste to account for 250g of chestnuts, then remove a mL of milk for every extra gram of paste you've added. If it's a substantial amount, replace some of the remaining milk with cream to keep it as rich as the original, if you like.

For example, according to the data I linked to, chestnuts are about 10% sugar, so you want enough paste to provide the 25g of sugar your 250g of chestnuts would've provided. So if the paste contains only 8g of sugar per 100g of paste, then you'll want about 300g of paste, and you can remove 50 mL of milk to balance the extra water you'll have added as part of the paste. (At that point it probably wouldn't be worth bothering to rebalance the milk and cream, since it's such a tiny difference.)

Why did my sauce get lumpy after being frozen?

Question

Two months ago, I made a fish sauce (roux + milk + fish stock + lemon juice + cheese + mushrooms). I made way too much, so I decided to put a good amount (0.5 l / about 2 cups) in the freezer.

I wanted to use it this week, so I got it out of the freezer, and I put it in a sauce pan on a low heat, when it was still frozen. However, the result after it was fully heated, was not so good: it contained lumps (but not roux-lumps) so not at all the desired consistency.

Why/how did the lumps got there? Was it because I didn't properly defrost the sauce? Or was it a consequence of the freezing itself? What can I do to avoid this the next time?

There were no lumps when I made it.

Answer

Assuming your roux is flour based, the original recipe mixture was able to be a sauce because the proteins in the flour formed gluten and created that lovely thickness we enjoy (your seasonings sound like a nice combo). The water from the other ingredients are trapped in the gluten. Unfortunately, when you freeze it, the water molecules form sharp shapes like knives and cut your gluten strands. This isn't a noticeble problem until your defrost it.

It doesn't matter how quickly or slowing you defrost. The damage was done when it was frozen.

To work around this issue, you have to freeze it faster! Professional establishments can super freeze things super fast. Freezing faster will make smaller knife-shaped ice crystals and that reduces the damage.

TIPS:

• freeze in smaller portions and shallower depth on a pre-frozen metal cookie sheet.

• Defrost and strain the sauce. Make a new roux and add the defrosted & strained sauce. The flavor comes from the frozen sauce and the new roux recreates the gluten.

Should scones dough be sticky?

Question

I decided to make scones for the first time and picked a high rated recipefrom allrecipes.com.

It instructed me to combine the ingredients like a pastry dough (cold butter cut into the dry ingredients, crumble, then add the wet ingredients). Then:

Turn onto a floured surface; knead gently 8-10 times. Divide into four portions. On ungreased baking sheets, pat dough into 4-in. circles. Cut each into four wedges, but do not separate.

I followed the recipe to the letter, using a scale. But the dough emerged extremely sticky. Kneading was impossible. Forming into circles too: I spread it with a knife, but couldn't get it in any way into a regular shape. It stuck to everything, including a silicone rolling mat and a silicone spatula. The best description I can manage for the consistency is Nutella-like.

Is this normal? If yes, why the "knead" instruction? If not, what went wrong?

Answer

It should be reasonably dense, firm and only a little sticky on the outside - a bit like modelling clay. You should be able to knead it easily and cut shapes out of it without too much trouble.

The absorptive potential of flour varies by brand and even batch, so recipes involving it always require a little improvisation - in this case it sounds like you need a bit more.
