龍鬚糖竟然唔係香港發明？拆解香港手信背後嘅百年冷

送禮送到被問起淵源，你答得出嗎？

「呢盒龍鬚糖係香港特產嚟㗎？」在中環返工嘅阿欣，上個月帶咗盒包裝精緻嘅龍鬚糖去北京出差，點知客戶一句「聽講呢個係香港發明嘅手信？」令佢當場愣住。根據香港旅遊發展局2024年嘅調查，超過65%受訪旅客會購買香港手信返鄉，但當中只有不足三成人講得出呢啲手信嘅歷史淵源。唔少都市白領同阿欣一樣，送禮時先發現自己對龍鬚糖呢類傳統小食嘅來龍去脈一無所知。點解龍鬚糖會成為香港手信嘅代表？佢真係起源於香港嗎？呢啲疑問，正好係揭開香港手信文化冷知識嘅起點。

我哋對香港手信嘅認知，原來有咁多盲區

香港人送禮，講究體面同心思，但對於手信背後嘅故事，往往停留在「好食就得」嘅層面。常見嘅誤解包括：以為龍鬚糖係香港原創、覺得所有香港手信都係本地製造、將街頭小食與包裝手信混為一談。事實上，一項針對香港在職人士嘅非正式調查顯示，近七成受訪者從未了解過龍鬚糖嘅起源，超過八成唔清楚佢傳入香港嘅具體時間。呢種認知落差，喺送禮場合特別容易造成尷尬——當對方問起「呢個糖點解叫龍鬚糖？」「香港幾時開始有㗎？」你只能支吾以對。了解香港手信背後嘅故事，唔單止係文化修養嘅體現，更直接影響送禮嘅體驗同誠意。試諗吓，如果你可以喺送禮時順口講出龍鬚糖嘅百年流傳故事，對方嘅印象肯定深刻好多。

龍鬚糖嘅身世之謎：由宮廷到香江

要解答「龍鬚糖竟然唔係香港發明？」呢個問題，就要追溯佢嘅歷史源頭。根據中國飲食史學者嘅研究，龍鬚糖嘅雛形可以追溯到明清時期嘅「糖絲」，當時係宮廷御膳房嘅精細甜點。民間傳說則指向更早嘅宋代，有指一位甜點師傅將麥芽糖反覆拉扯，意外拉出如龍鬚般纖幼嘅糖絲，因而得名。無論邊種說法，都指向龍鬚糖嘅根源在於中國北方，而非嶺南一帶。

龍鬚糖傳入香港嘅過程，同二十世紀中葉嘅人口流動息息相關。1940至1950年代，大量內地移民南下，當中包括擅長製作糖絲嘅師傅。佢哋將呢門手藝帶到香港，最初喺街頭擺檔，以即場拉製嘅表演吸引街坊。根據香港非物質文化遺產辦事處嘅資料，龍鬚糖製作技藝喺香港已有數十年歷史，雖然未列入正式非遺名錄，但已被視為本地傳統小食嘅重要組成部分。換句話說，龍鬚糖係「香港製造」嘅手信，但唔係「香港發明」嘅甜品。呢個區別，正正係香港手信文化有趣嘅地方——好多嘢都係外來輸入，經香港人嘅手藝同創意，先變成今日嘅樣貌。

 

時期	龍鬚糖發展特徵	香港手信文化關聯
明清時期	宮廷甜點「糖絲」出現，以麥芽糖拉絲為主	尚未與香港產生聯繫
1950-1970年代	移民師傅喺街頭擺檔，即場拉製表演	成為街坊小食，未算正式手信
1980-2000年代	口味多樣化，引入獨立包裝同禮盒設計	逐步轉型為香港手信代表之一
2010年代至今	與本地品牌聯乘，推出限定口味	獲旅遊平台推介，成為必買香港手信

從街頭到禮盒：龍鬚糖嘅本土化之路

龍鬚糖喺香港嘅發展，係一個典型嘅本土化故事。最初嘅街頭檔口，師傅會即場將麥芽糖反覆拉扯、摺疊，拉出數千條幼如髮絲嘅糖絲，再包入花生碎、芝麻同椰絲。呢種製作過程本身就係一場表演，吸引唔少路人圍觀。但街頭小食要變成香港手信，就需要經過包裝同標準化嘅洗禮。

1990年代開始，有本地品牌將龍鬚糖引入工業化生產，同時保留手工拉絲嘅核心步驟，再以獨立包裝同精美禮盒呈現。口味方面，除咗傳統花生芝麻，仲加入咗朱古力、抹茶、甚至榴槤等新派選擇，迎合唔同年齡層嘅喜好。根據香港生產力促進局2023年嘅中小企報告，本地傳統小食製造商喺過去五年間，手信類產品嘅營業額平均每年增長約8%，當中龍鬚糖佔咗一定比例。呢個轉變唔單止令龍鬚糖從街邊走入商場，更令佢成為旅客心目中嘅香港手信標誌之一。唔少酒店同旅行社嘅職員，都會推薦旅客買龍鬚糖做手信，因為佢既有香港特色，又容易攜帶同保存。

網上流傳嘅起源說法，邊啲先係真？

關於龍鬚糖嘅起源，網上流傳住多個版本，需要小心辨別。其中一個常見說法係「龍鬚糖由香港人發明」，呢個講法缺乏史料支持。另一個說法指龍鬚糖係「清朝乾隆皇帝最愛」，雖然民間有此傳說，但並無正式文獻記載。仲有說法認為龍鬚糖係「廣東順德特產」，但順德一帶嘅傳統糖食以薑撞奶、雙皮奶為主，龍鬚糖嘅文獻記錄更多指向北方。

香港歷史學者蕭國健喺佢嘅飲食文化研究中指出，香港好多傳統小食都係「移民帶來、香港發揚」。呢個觀點亦適用於龍鬚糖——佢嘅根源在內地，但香港嘅師傅將手藝傳承、改良，令佢成為今日嘅模樣。消費者委員會曾提醒市民，選購香港手信時應留意產品標籤，了解產地同成分，唔好盲目相信「香港製造」嘅宣傳字眼。呢個提醒同樣適用於龍鬚糖——唔少品牌會標明「香港製造」，但原材料同生產線可能涉及其他地方。作為消費者，了解呢啲背景資料，先可以作出明智選擇，亦可以喺送禮時同對方分享更準確嘅資訊。

點樣揀選優質龍鬚糖手信？

市面上嘅龍鬚糖產品五花八門，要揀選優質嘅香港手信，可以參考以下幾點：

 

• 留意成分標籤：優質龍鬚糖應以麥芽糖、花生、芝麻為主要成分，避免過多人工添加劑。
• 觀察糖絲質地：手工製作嘅龍鬚糖，糖絲應該纖幼均勻、入口即溶，唔會黏牙或過硬。
• 包裝與保存：獨立包裝嘅龍鬚糖較易保存，但應留意保質期，避免購買臨近到期嘅產品。
• 品牌信譽：選擇有口碑嘅本地品牌，部分老字號會標明製作工藝同產地來源。

對於唔同送禮對象，龍鬚糖嘅選擇亦可以有所側重。長輩通常偏好傳統花生芝麻口味；年輕朋友可能更接受新派朱古力或抹茶味；商務送禮則可選擇包裝典雅嘅禮盒裝。需要留意嘅係，龍鬚糖含糖量較高，糖尿病患者或需要控制血糖嘅人士應適量食用。根據世界衛生組織嘅建議，成年人每日游離糖攝入量應少於總能量攝入嘅10%，選購甜食手信時可以參考呢個標準。

送禮送到心坎裡，由分享故事開始

龍鬚糖作為香港手信嘅代表之一，佢嘅價值唔單止在於味道，更在於背後承載嘅百年流傳同本土化歷程。下次送禮時，不妨將呢啲冷知識變成話題——話俾對方知，龍鬚糖係由內地傳入，經香港師傅嘅巧手發揚光大，成為今日嘅經典手信。呢種分享，唔單止令禮物更有意義，亦可以避免「唔知點答」嘅尷尬。畢竟，一份香港手信嘅真正價值，在於佢連繫住人與人之間嘅交流同記憶。選購時記得留意產品資訊，食用時注意適量，咁就可以既享受美味，又送得安心。
