This month’s round of TGRWT is hosted by John Sconzo over at Docsconz, and the foods to pair this time are pumpkin and cooked chicken.* As always you can find instructions on how to participate in the announcement post. If you are new to TGRWT (which stands for They Go Really Well Together), check out the round-ups of the previous 19 rounds!

* In case you wondered why the link to the announcement posts includes lemon grass: There was some confusion regarding how to read the charts at the foodpairing website. The initial suggestion was to use pumpkin and lemon grass, but his has now been changed to pumpkin and cooked chicken.

For this month’s “They go really well together” event (TGRWT #16) hosted by Supernova Condensate I decided to leave the chicken untouched and focus on the rose component. I had long wanted to try Chad’s Lemon whip (which I’ve included in Texture) where lemon juice is thickened with xanthan and then whipped to a thick foam after addition of methyl cellulose. I started with water, a little sugar and about 10 g of rose water. Having added xanthan and methyl cellulose I tasted it and decided to double the amount of rose water, add some more sugar and add a little lemon juice for acidity. I can imagine that rose water comes in differents strengths so it’s advisable not to add all from the start.

Rose foam
15 g sugar
0.7 g xanthan (0.49%)
100 g water
20 g rose water
8 g lemon juice
1.2 g methyl cellulose (0.84%)
(I used Metil from Texturas)

Grind sugar and xanthan. Sprinkle into water, rose water and lemon juice with hand mixer on full speed. When the xanthan is dispersed add methyl cellulose a little by little with the mixer still on. Mix for another 5-10 minutes until bubbles are small and uniform and the foam is dense and stable. If desired the foam can be whipped with an iSi whipper charged with nitrous oxide. I served the rose foam with diced apples, stalk celery and chopped almonds as a side dish to roasted chicken. Mashed potatoes with basil leaves, topped with a good olive oil and ground pepper was nice with the chicken.

Verdict: The rose foam is thick and lucious. The rose aroma blends very well with apple aroma. Lemon, almonds and celery give a nice contrast. The overall combo was a pleasant surprise! My previous encounters with rose water have been somewhat overpowering (especially in food from the Middle East), but the rose foam was much milder as I had diluted it with plenty of water.

The foam is stable on the time scale of minutes to hours. When left overnight the bubbles coalescese, but the volume of the foam remains more or less the same. Foam from the previous day can easily be whipped up again with a hand mixer.

The next TGRWT challenge has been announced: chicken and rose! Head over to astrophysics blog Supernova Condensate and read more on how to participate in round 16. And do check out the excellent summary of the dark chocolate and smoked salmon contributions from TGRWT #15 over at Mex Mix.

The suggested temperature range for the roast beef was from 60 °C for a pink interior to 68 °C for grey meat. I settled on 63 °C. I was a little optimistic regarding the timing, so when our guests had arrived and I checked the meat (after 1h 30m) the core had only reached 53 °C. First lesson learnt: meat is a poor heat conductor. I quickly figured that my guests would become very hungry if I were to wait for the core temperature to reach that of the water bath. I therefore turned the water bath up to 68 °C, and put the meat back into the water bath – this time in a normal plastic bag and with a temperature probe at the core. This worked surprisingly well, the pressure of the water pushing out all the air. After another 45 min it had reached 62 °C and I removed the meat from the water bath, saved the juices for the gravy, rubbed the meat with salt and pepper and gave it a quick pan sear with plenty of butter. Despite my bad timing the beef came out extremely moist and tender – I dare say that I have never before achieved such a result with a roast beef in my kitchen! And being my first attempemt at sous-vide with my immersion circulator it was extremely satisfying.

Today I prepared the chicken breast, and I figured that 1h 30m should be sufficient for 700 g of meat. The chicken came out very nice as I served it with fresh pasta, a curry sauce and some salad. Again the meat was moist and tender – and so different from most of the chicken I’ve prepared both at home and been served at restaurants.

I should also mention that I made 68 °C eggs this morning. I left them in the water for 1h. The egg white was very soft – almost runny – whereas the yolk had set but was still very pliable. Comparing this with the eggs over at Fooducation it’s clear that even with constant temperature time does play a role. My 1h @ 68 °C eggs had a white that looked more or less like the white of Erik Fooladi’s 6h @ 65 °C eggs. The are probably several reasons for this, but I guess that the kinetics of protein coagulation are mcuh more complex that one might expect at first. But that’s a different story.

Several comments to my last post asked about pricing and where to buy immersion circulators. Basicallyl any laboratory supplier sells these. And even the simplest models have temperature stability of +/- 0.1 °C or less. Amazon also has a couple of models available from Fischer/Thermo Scientific ranging from around $900-2000.
