extremely fresh
Correct. Unlike many other KSML options, their meals never claim to be serve-able for more than 2 days after production (none of this "long-life" crap), so it's bound to be fresh.
Beware that TK does not use them 100% of the time, though. For CMB-MLE-IST, for example, they often have the Sohar long-life meals, as the plane has been sitting in CMB for 24-48 hours at that point and they don't have any way to source a fresh meal from La Casa De Barınyurt from there. And believe me, the packaging of those meals tastes better than the meal itself.
