I need a bit of advice translating metric units into "American" units for a recipe I keep using. My main problem is converting grams (weight) into tablespoons and teaspoons (volume).

Here's the recipe: Kale with baked eggs.

I can do metric measurements for everything, but the 40g butter and 40g plain flour for the roux. What would these be in T or tsp?

I've been using my usual roux recipe, but I'm curious to what the measures really should be.

I use this dish as a main course sometimes too, but for Christmas dinner I served it as vegetable dish alongside poached salmon.

I fear this is a hopeless quest. Tablespoons are a liquid measure anyway, see da wiki da pedia.

40 gm = 1.41 oz

Is there any hope this might help? .....?

After messing about in my laboratory kitchen, I have reached the conclusion that you need approximately

6 level tbsps of flour (to equal 40 gm)

but the butter is beyond me. Roughly 1 and a half ounces...

And these is cheese-eating surrender monkey tablespoons.

According to this site, my 6 level tbsps seems right for the flour (6.4 US tbsps with US all-purpose flour, you can't say better than that).

Butter is between 2 and 3 tbsps.

I'd be tempted to do 7 level tbsps flour to 3 level tbsps butter.

I'll handle the "butter issue"; I'll leave the flour to someone else (for now).

To solve this problem we need to know ... dum dum dum ...  the DENSITY of butter so we go to WIKI (who we trust?) which informs us that the density of butter is .911g/cubic cm.  To get to tsp, once again WIKI states that 1 tsp = 4.93 mL (= 4.93 cubic cm) so

Dimensional Analysis Time !!! (wooo wooo!)

(Note:  True Nerds ALWAYS go wooo wooo when it's time to change units.  It's part of the code.)

40 g x (1 cc/.911 g) X (1 tsp/4.93 cc) = (calculator please ...)

9 tsp (yes, only 1 significant figure; that's what you have in 40 g.)

So, your 40 g of butter translates into 9 tsp.

The logic will be the same for the flour; you need the density of the flour and then the appropriate conversion factor to T.

Will post this part then take a shower.  If someone else doesn't jump in I'll do the flour in a bit.

CHEM NERDS ... accept NO substitute!

Those are teaspoons? Or tablespoons?

Hey, don't chem nerds just have simple tools to weigh stuff in grams? (Like quaint Yurpeens do, in their kitchen?)

Come back after shower. :-D

This butter problem was a conversion to TEASPOONS!!  NOT ... I emphasize ... NOT Tablespoons (the bigger guys.)  I'll do the flour (in a bit) to T(ablespoons)

I need you to convert bushels of corn into metric tons. You'll need the density refs again. It's fascinating.

The only people I once knew who had scales to weigh gram size things were selling weed and the like (decades ago in college).  I don't weigh anything when I cook.  And Truffles says "Hello" to all her European fans.

Well, I suggested 3 level tablespoons of butter, which is 3 x 15 = 45 ml/cc, which divided by your 9 teaspoons does indeed work out at 5 ml/cc or (to one significant figure) 4.93 ml/cc, so we in fact agree despite your nerdiness and strange American system of measures.

How can anyone cook using cups, tbsps, and tsps, especially when no one knows how much they are and they differ across the quaint old English-speaking world?

The 5 is the one significant figure. 4.93 -> 5.

Because we have brains the size of planets.

AND we know our 64 times tables.

Actually, it really doesn't matter.  The original ingredient list is only approximate.  Depending on the ambient air temperature, humidity, real eggs versus battery raised eggs, Holstein milk versus Jersey milk, etc., etc. the actual As-Made list will be different for each iteration.  As long as the first set is more or less correct in ratio ... it'll work out.

Intuition and experience, that's how.  Fiddle with any set of measurments long enough, and KNOW what you're trying to make on a deep level, and these things just become sort of obvious.

After reading responses to your request, Magnifico, you may wish to revert to your usual roux recipe.

If it works, don't fix it.

to quote an award winning chef and friend of mine, you dont do things like that by recipe, you do them till they look right. mix your butter and flour together till you have the right consistency, by sight, then add milk till that looks right.

Any idiot can face a crisis - it's day to day living that wears you out.

Well, that's cool if you make roux really often. For most of us, having quantities of butter and flour that fit with (in this case) a half litre of milk, is helpful.

What the devil are you going to do with 600ml (more or less) of roux?

BTW, the secret is equal amounts, by weight, of fat and flour.  Doesn't matter what fat as long as it is compatible with the rest of the ingredients of the dish.  Most people always use butter or/and milk cuz they are wusses, unadventurous stick-in-the-muds going for the mediocre.

The half-litre is from the recipe Magnifico is using. Presumably Fearless-Twittingstall from the Guardian knows what he's going to do with that much béchamel. Or mornay, since he's putting cheese in it.

Actually, true roux ingredients are not measured in T or tsp, rather half snake skulls. Mixed with ground bone and hair, and herbs gathered at midnight on a full moon.  Allowed to dry after cooking, and sewn into bags placed under enemies pillows.

Likely, however, you meant the cooking roux, not the gris gris stuff.

i go now.  (PS. nice recept, sounds delicious, yes i read it.)

That one's duck, not goose. Though the size was in goose territory.

There's not much left. No, it has lost savour. It was best when first dug out of the fat and cut into. Either that or I've had so much fat duck my palate's jaded. Dat's a serious possibility.

Here we go:

40 g of flour to T(ablespoons)

From WIKI, density of wheat flour is .5 - .6 g/mL ; let's go with .55 g/mL

ALSO, 1 T(ablespoon) = 15 mL   so

40 g x (1 mL/.55 g) x (1 T/15 mL) = 5 Tablespoons

So your 40 grams of flour translates to 5 Tablespoons.

Enough nerdiness for one day.  Football is on.

Bye

Talk to the WIKI folks.  I'm just the number cruncher who makes sure the units all work out.  It's what I tell my students; "The units are your friends.  Use them!"
