Published by Packaged Facts in collaboration with the Center for Culinary Development (CCD), the report states that "adding a twist of indulgence to ordinary foods and beverages generates consumer interest and new business opportunities".

"American consumers have become comfortable indulging through non-essential, yet accessible, consumer experiences via pleasurable food and drink," said Kimberly Egan, chief executive officer of CCD.

The report - Indulgence: Culinary Trend Mapping - reveals how the concept of indulgence has moved away from its original association with 'fattening' products.

The term is now linked to an expression of sophistication and a sincere appreciation for handcrafted quality, said the report.

It provides "important emotional benefits that translate into profits", such as "über comfort" and "the thrill of trying something exquisite", it said.

The report identifies a number of trends within the category, which it says "enhance the appeal and emotional satisfaction" of products.

Taste Adventure

This involves introducing consumers to novel flavors and textures.

Examples include infusing floral flavors such as jasmine, rose and hibiscus, which can transform a familiar product into a "fresher, more natural treat".

In addition, creamy Greek yogurt - rich in protein and probiotics - is a "luxurious upgrade" of an American staple.

Truffles are another example highlighted by the report, which suggests that domestically-produced products now give a "no-travel" taste of France.

Connoisseurship

As consumer confidence and consumption of wine increases, this has started to appear in a growing number of products, such as wine-flavored chocolates, ice-creams, syrups and sauces, which even feature varieties such as cabarnet.

Artisanal Connection

Knowing where products have been made or sourced from has emerged as a sign of premium quality.

According to the new report, flagging up products as 'single origin', 'fair trade', 'handcrafted', and 'farmstead fresh' can make a big difference to consumers seeking something more special.
