Well, Moroccan mint tea to be more precise as he admits he has yet to taste a good English cuppa - something his new team-mates have also failed to sample over the last five years.
He misses the perfect brew his younger brother used to make for him at his Moroccan tea rooms business in Bordeaux.
Chamakh even worked as a barman at Yassin's Salon de The twice a week before his free-transfer switch to the Emirates in the summer.
"I like to give my little brother a hand and I served the cold drinks," says Chamakh.
"The tea I left to him because I don't know how to make it well.
"We served specialist Moroccan teas and the mint tea is VERY good."
Better, even, than the £2 Arsenal tea bags sold in the club shop.
"Yassin did not pay me, I did it for love," he adds. "But it was a shock for some customers to see an international footballer serving drinks there and some would ask for my autograph.
"However, it was not a surprise for people who really knew me. It helped keep my feet on the ground.
"And if I was to become a bit big-headed my friends would take the mickey out of me."
Char-makh could also have helped his brother with the books as he has an A-level equivalent in accountancy.
But you don't need to be a mathematician to work out the importance of today's game.
Since Arsene Wenger's Invincibles won the Premier League, the Gunners have won just two of their 15 meetings with the Blues.
Chelsea won both Premier League clashes last season without conceding a goal, while Blues striker Didier Drogba has scored 12 goals in 12 games against their London rivals.
Figures not lost on the keen maths student.
Strength
"Yes, I was aware of the record. Arsenal played well in those games but didn't win," he says. "We need to show a bit more mental strength, focus only on this game and not be distracted by past results."Both teams are able to score goals, but the team who defends best will win the match."
But defending has been something of an Arsenal weakness in recent seasons.
"It is true that in defence we could do better," he admits. "But it is not just the four defenders and the goalkeeper.
"As the centre forward I am the first defender and it is something that all 11 of us need to co-ordinate together.
"We have to prevent Drogba from causing us any problems."
However, Chamakh does not have fond memories of his previous two games against Chelsea - both in the Champions League when he was at Bordeaux.
They drew 1-1 in France, but Bordeaux were spanked 4-0 at the Bridge.
"Chelsea were stronger, faster and more aggressive," he recalls. "But without any disrespect to my friends at Bordeaux, this Arsenal team is better equipped to play Chelsea."
Chamakh will have to find a way past England defender John Terry, something even the world's best have failed to do.
"John Terry is a player I appreciate," says Chamakh. "He is a very good defender and it is going to be really tough."
But Arsenal's 26-year-old striker insists he won't resort to kicking him. "No, I will try and disturb him, I need to move as much as possible in order to really rattle him but what is important is that I don't focus just on him."
Possibly to help plan his strategy, Chamakh is reading the autobiography of former Moroccan army general Ahmed Dlimi.
He died in a car crash in January 1983, although some claim he was assassinated.
It's not normal reading material for your average Premier League footballer. But then Chamakh is not your average footballer.
Although born in Tonneins, France, he's fascinated by the history of his parents' nation. It is one of the reasons he opted to play his international football for Morocco while plying his trade in France as a 19-year-old.
FORM: Scoring in the Champions League
He is also very keen on politics. Earlier this year he joined the Democratic Movement Party of France and put his name forward as a candidate in a regional election. This is what party leader Jean Lassalle had to say about Chamakh's political savvy: "Marouane has not just been made to score goals - he has things to say as well . . . He is a bloody clever guy."
In the end Chamakh did not stand, but was still very vocal in his backing of the party's Bordeaux candidate.
"I am really interested in politics," he says. "I supported the Bordeaux candidate because he was someone I knew and because his manifesto was based around sport, how money raised by taxes would be spent on sport. I place myself on the left wing in political views."
Left wing he may be, but when it comes to religion, he's more centre forward. As a practising muslim he fasts during Ramadan - except on match days.
"Religion is very important to me," he says. "I am used to fasting, I have done it for so long, it does not have any impact on my training and it does not make me weaker for games. My body is used to it."
He also likes to "sleep a lot, surf the internet and play PlayStation games" - useful as he's the latest ambassador of EA SPORTS' new FIFA11 video game.
There are already a number of websites devoted to his distinctive hairstyle though he admits: "It only takes me five minutes."
About the same time as it takes to brew a really good cuppa.
And if Chamakh helps Arsenal beat Chelsea today he might even toast the win with a cup of char.
