If you want the best baguette in Paris, go see Ridha Khadher. The 42-year-old baker has been turning out the long, golden rods of bread since he was 15, and recently was awarded the Grand Prix for his labor.

Khadher decided at the last minute to enter the annual competition for the best traditional baguette in the city.

He was among 203 candidates, though 52 were swiftly eliminated for failing to meet strict criteria that include length of the baguette — 55 to 65 centimeters (21.6-25.5 inches) — and weight — 250-300 grams (8.8-10.5 ounces).

Besides the acclaim, and likely extra business, the winner gets to deliver his baguettes to the French presidential palace for a year.

His secret is not the ingredients, because they don’t change, he said. “The secret is hard work,” he said. An excellent baguette depends on how the dough is kneaded, how long it rests, and how it is shaped, he said.

His traditional baguettes are nearly 24 hours in the making, compared to five hours for ordinary baguettes. Khadher and his crew turn out 800 to 1,000 baguettes a day in the basement furnaces of his Left Bank shop, Au Paradis du Gourmand.

Khadher came to France at the age of 15 from Tunisia and quickly entered the bakery business with his brother, becoming an artist of the most French of symbols.
