Michael Russell included JinJu in The Oregonians 2019 overview of Portland's best croissants. Willamette Week included the bakery in a list of "12 things that didn't suck" about 2020. A food writer for the newspaper said, "For aficionados of laminated pastries, JinJu is a precious gem. The best known variation is the croissant, which at JinJu is dark, golden-baked, buttery perfectionâÂÂif you can get your hands on one before they sell out. But the crown jewel of the lot is the weekend-only gianduja kouign amann, a carmelized sugar-encrusted, crown-shaped pastry with a center core of hazelnut-kissed chocolate cream. It is truly world class. Order it and you might forget for a moment that it's still 2020." JinJu was a runner-up in the Best Bakery category in Willamette Week annual 'Best of Portland' readers' poll in 2024. It was a finalist in the same category and won in the Best Sweet Shop / Chocolatier category in the same poll in 2025.

Nothing beats the showstopper that is JinjuâÂÂs lemon-raspberry tart, a crown of toasted meringue surrounding a core of silken raspberry-lemon filling, cradled in a buttery pastry crust." Rebecca Roland, Kara Stokes, and Janey Wong included the "brown-kies" in a 2024 list of Portland's best "decadent" cookies.
