Yay!
Raez thinks about it for a second before asking, "Oh yeah, do you want a recipe for ice cream? I can write one out if you'd like." 
The narrator likes that the packet (or whatever remains of it, judging from the general charred base under the flames) is dead silent now that Ramma is actually wearing ear plugs.
"Oh yeah, you can't hear me," he muses after a while. 
...yeah. 

"is liquid cream the same as water cream?" Raez asks back on impulse. He then takes a pause and then uses his hands (which have been free for a while) to gesture at his ears. 
You should just get away from the fire. 
 

"Do you want to add some sugar? I heard sugar makes everything better."
Your friends are not credible sources for information.

Raez nods real sagely for a guy who just suggested adding some. "Okay, then maybe just a pint then." 
I do not think he knows units of measurements very well.

"It does, but a tent is probably a tad too much. I think it's a unit of measurement. Like the ligne, you know? Or the hand. Or a horse. Or a football field."
He lectures like he knows what he's saying. 
"I think I have some sugar packets somewhere," he adds, rummaging in his pockets. "Or maybe chocolate? Which one would you like better?"

"What kind? I have a few. Actually, let me show you." Raez finally stands up (how he didn't get stiff-necked in that position is beyond me) and rummages in his other pocket, finally pulling out three rather comically different types of choclate: A large bar of milk chocolate ("1000% SUGAR!!!!" printed in bright yellow font across black wrapping), a singular small piece of dark chocolate wrapped in a very normal wrapper, and then what looks to be a rock-solid piece of military rations chocolate in a transparent plastic bag. 

Raez holds the corresponding bar toward Ramma. "Okay, you can have half."
After a brief pause, he adds, "Half because my friend said his heart would be shattered into a million pieces if I kept giving away his gifts to me as gifts for others." 

It's Raez's turn to blank for a second before he beams, "Thanks! I don't hear that often." 
He sits back onto the ground. "I hope the ice cream turns out well." 

"Great question! Lemme see." 
Raez puts his hand directly on the metal.
"Well, it feels pretty hot, so I reckon well."
